shopping, which one?

The D3 supports an ISO of up to 25600 which is CRAZY!!!!! I have a strong feeling that is going to be a sign of what we can expect to get in the 1000 dollar range in a year or so. It is full frame size which is really good. The bad, all those digital lens that lots of people are building collections of dont work properly on full frame cameras. It is why I try to stick with film SLR Pentax lenses. That way when Pentax/Hoya comes out with full frame at a crazy low price, my lenses will be good to go.
Since Canon has been shipping full frame cameras for many years, it's really not an issue for them. As long as the lens is an EF mount it doesn't matter what size the sensor is.
The D3 is a good first step for Nikon but I was surprised to see the resolution so low.

All EF lenses, from the dawn of time, are full frame.
EF-S, is a different mount designed for smaller sensors. You have to remember that Canon has been shipping full-frame cameras for a LONG time.
Not the mount, the design of the lens elements. The EF-S lens series are the lenses that are designed specifically for Canons non full frame digital cameras. These are the mainstream lenses that you will find most Rebel, Rebel XTi, etc owners have. Those lenses will not work properly on a full frame SLR. That was the point I was getting at. Alot of DSLR owners have build collections of these types of digital specific lenses, that wont work with the next generation of Full fram DSLR cameras.
While that might be an issue with Nikon, it's not an issue with Canon. Like I've said several times, Canon has been shipping full-frame cameras for a very long time. Their EF-S, digital only, lens portfolio is currently 5 low-end consumer lenses. The EF line, which works on everything, is ~60 lenses.

That is why all my Nikon lenses are full frame, not concerned about weight...which is the only real reason to have ever bought a "DX" lens. (oh, I do own a Tokina 12-24mm that is not full frame). Figured eventually Nikon would have to put out a full frame camera.
Almost made the switch to Canon last year, had the shop I stopped at had a 5D in stock the process would have begun...and would have happened over time if not keeping both systems.
Canon high end was beating Nikons...but when your talking the entry level (D40, D80, 20D, 30D) there is no difference in noise capabilities between the two. Canon gets you better colors out of the box if shootin RAW due to their not keeping the coding secret from Adobe, a big advantage...but if shooting in JPEG or TIFF not a concern.

So correct me if I'm wrong but this is a huge benefit of the Pentax, because the K10D is compatible with all the old K-mount 35mm full frame lenses, and even other style mounts with an adapter. So this would lead one to believe that Pentax will continue its backwards compatability when it releases a full frame, so you could use any K-mount digital lenses when you upgrade.
Ok, I will. 
You're kidding yourself.
Like I said before, full frame lenses make up almost the entire Canon line of lenses (~60). EF has always been full frame compatible and will continue to be so.
The EF-S lenses, all 6 of them, are sold with the consumer, entry level cameras (i.e. XT, XTi). I don't know anyone, who shoots seriously, that uses any of that line.
Now take a look at Pentax. It's true that you can use your old K mount stuff, with limited functionality, just like you can adapt old Canon F mount lenses for current cameras. All of Pentax's new lenses are the "DA" line. They're all for AP-C sized sensors.
The Pentax is a fine camera and I know folks who use them to take excellent pictures. That said, the logic that you're using to defend your use of it make very little sense. If you like it and get good results, continue using it.
Cheers

Not trying to defend my choice, I'm very happy with it fundamentally because I think it has equal image quality and superior features to comparably priced canon/nikon options. Just trying to understand how the backwards compatability factored into it, because admittedly, this still isnt clear to me. From what I understand, I can use old Pentax 35mm lenses (albeit without autofocus) on the K10D, but I did not think the same was true for Canon. So Pentax releases a full frame, what would happen if I use the DA lenses with a full frame? And what is the effect of using Canon's full frame lenses with their consumer DSLR format?

Correct me if I'm wrong Nikonians but I believe the Nikon system does not even require an adapter. The Pentax and Canon systems do. As has been mentioned, you lose some functionality with the older lenses.
If/when Pentax releases a body with a full frame sensor you will lose the lens multiplier and be back to normal, so to speak. The lens multiplier is great for wildlife and close-ups and terrible for landscapes and architecture.
The effect is what's known as the lens multiplier. For Canon's prosumer cameras (D60, 10D, 20D, etc) it is a 1.6x multiplier. That means 100mm will seem like 160mm. I have a 100-400mm zoom lens and it acts like a 130-420mm zoom lens on my 1DMII because it's a has 1.3x multiplier [8mp]. If the sensor size changes significantly so does the lens multiplier.

If they physically fit the camera, most "Digital Only" lenses will cause vignetting on a full frame sensor because they project a smaller image circle. An example of that is the Tokina 12-24 (which is basically the Pentax 12-24 DA with different paint). The Canon version is a digital only lens but is an EF mount. While it will physically fit on my camera it's only usable from about 17mm-24 because of vignetting.

GregR, your correct...Any nikon lens will fit any nikon camera (well SLR's made after the 1950's) the only issue you will run into shooting one of the Nikon DX lenses with a 35mm film or full frame digital camera is vignetting around the edges which depending on the lens could be slight or as the case with the 10.5mm very unusual and large.
It should also be stated that the DX lenses can still be used on the D3 only in the "High speed crop" mode which now will take up the old DX sensor size ignoring the rest of the sensor. The photographs will be a smaller size as with the D2x it went from 12.2 to 6.0 I assume the same is true with the D3.
