But Wait, There's More NVIDIA G92 for 2007 (8800GTS 128SP)

Here's what I think might happen:

Or, IIRC, the G80 was touted as having the capability of reaching 160SP's but thermals, cost, and power could not work on the 90nm process. With 65nm, they might see if they can expand the G92 to 160 SP's with new revisions and increase shader clocks as well, and make a new GTX/Ultra. Then we'd be back at GTX>GTS>GT. If you use how Nvidia calculates flops, a GTX with 160 SP's at 2000 Shader Clock is ~1TFp (3 x 160 x 2000 as they calculate it) and voila, you have that magic 1TFp card of ancient lore everyone talks about.

Mmm, it's quite possible the next generation will have 192 SP and 2400Mhz Shader clocks.
