I'm gonna copy and paste from several posts I've responded to, so hopefully they will clear some things up.
I'm guessing the new GT200 will be a dual core architecture similar to AMD's RV670, but will support native 64-bit floating points (FP64) unlike the RV670 (how sad lol).
You guys can more than likely expect it in September 08, as this is 6 months from the 9800GX2 release - but I'm guessing Nvidia will just delay it until November to get back on track with their high end November launch schedule.

New rumors say its gonna have 64 ROPs, 256 TAUs, and a total of 1024 shaders. 1024Bit design, 2GB DDR4 memory
There's no way the card will have 64 ROPs, as there's no use for them - I would expect to see around 32 at most. A 1024-bit design would be nice to have, but even that would be pushing the new PCI-Express 2.0 spec to the limit - yet another faulty claim. Consequently, 1024 shaders aren't likely to exist - I would expect the number to be no more than 384. The only true claim so far would be 2GB of DDR4 memory, but even then, Nvidia might skip straight to GDDR5. Based on an analysis I've read, few suggest that "the first GPUs based on GDDR5 could possibly be released in late Q2 or Q3. Of course, that also depends on NVIDIA and AMD's roadmaps, and whether that makes sense in their current plans." If this assumption is true, this would bring to light the claim that the GT200 is in fact going to be released around September as I predicted. It would nice to see GDDR5 not only for the bandwidth, but also because Samsung is claiming 6GHz speeds for its highest end chips. And finally, the best part about the new GT200 architecture is that it will allow for double-precision 64-bit FPs, which will bring great performance leaps in just a few months to come.

lol, the 8800GTX / Ultra were #1 for..... how long?
launched: Nov 8, 2006
still # 1: Feb 23, 2008
according to that thing it will be best until:
March 11, 2008
..so that makes it # 1 for 17 months..... wtf.
That's because Nvidia "skipped" an entire launch sequence in 2007 by continuing the GeForce 8 series up until now. Even more so, the 9 series is simply a die shrink/refresh (similar to Intel's "tick" "tock" method), and therefore we aren't even going to see any true architecture improvements until GT200 which is close to 2 years after the launch of GeForce 8.
However, in a normal sequence of product launches, Nvidia (and ATi) typically will launch card successors within 6 months of each other (7950GX2 in May 06 > 8800GTX in November 06 > 8800Ultra in May 07 > G92 8800GT in November 07 [if used in SLi]). Also note that the 9800GX2 was originally scheduled for November 2007, which would make it close to a ~6 month successor to the 8800Ultra - however, there were delays - November turned into late January, which turned into February 14th, which now turned into March 11th. sad
This makes me wonder if Nvidia will release the GT200 in September (6 months from 9800GX2), or if it will compensate for time issues and delay it until November.
