Thanks for your help everyone. We're porting over from Pentax, and as a result neither are really familiar with the intracies of the Nikon stable of lenses. We know that we'd like a constant f/2.8 in this focal length though.
Are we on the right track looking for an 80-200?. I've read a review or two claiming that the 70-200 is less than stellar at the corners when paired with a D3 or D700. I would rather spend less on a less technologically advanced lens if it means the overal optical performance is better.
Thanks again for your help, and please keep the input coming. And if anyone has used the 70-200 on FF let me know your impressions as well!

The 80-200 is good pro-quality glass. The 70-200 is much, much better pro-quality glass. I can't really answer for you if it's worth the delta in price. However, I'll say that I actually believe that the fuss over the 70-200 on full frame is over-done. Nikon's official answer is "vignette control," but I suppose a lot depends on what you're shooting with it as to how pronounced it is- but it'll likely be there with both lenses.
Here's an interesting thread...

The vignetting is going to be most noticeable in evenly colored skies and walls, so if you're shooting in those conditions, you'll see it. It's fixable in PP as well. I've looked at a couple hundred FF images shot with the 70-200, and I think it's an issue in less than 5% of them out the box- YMMV.
I got the 80-200 because I wanted a small "walk-around" lens, if I regularly shot seriously in that focal length, I'd have bitten the price bullet for the 70-200. There's no telling if Nikon will issue an updated 70-200 with a wider or brighter image circle, but if it happens, it'll probably have to happen in the next six to ten months. The 80-200 is a fair hedge for that, though you'll give up sharpness and contrast, especially with the AF-D versions. However, you should be able to get close to what you pay for it if it's an AF-D version, and worst-case it's a good backup.
If you plan on shooting a lot of stuff soon, and you're making some money with it, then I'd probably go with the 70-200 for overall IQ. If it's a 20% or less focal length, I'd go with an AF-S 80-200. If it's just for fun, or 10% or so of your shots, then I'd look at AF-D 80-200s. If you're shooting weddings or sports, this is the season, and I wouldn't skimp since what you get this year will be a lot of your marketing for next year.
The production cuts Nikon made for the economy has everything in short supply- if there was ever a good window for changing the 70-200, this is it. They actually cut too much, but that means there's not a huge pile of lenses sitting around.
