What I had said before still stands. I'll believe it when I see it.
As far as an upgrade path, OK, that might be coming. Again, I'll believe it when I see it. What I DON'T believe, however, is an upgrade path to the 8800M. As I had said previously, the heat and power requirements of the G80 are absolutely ridiculous. Go look up a detailed review of the desktop GeForce 8800 GTX or Ultra and you'll see what I mean. Then, go look up a review of the GeForce 7900 GTX desktop card (which is pretty close to the GeForce Go 7950 GTX) and compare the two in terms of heat and power.
In order for NVIDIA to make an 8800M, they'd have to do one of two things:
1.) Lower the GPU/Memory speeds so much that it would make the 8800M less than worth-a-crap in performance. Or...
2.) Defy the laws of physics by fitting that monster in a laptop chassis and STILL making it cool enough to run in such a confined space with adequate cooling.
Either way, I just don't believe there even WILL be an 8800M. With G90 on tap for November (hopefully) I believe there's more likely a chance that we'll see a 9800M. That would be something to talk about.
