Looks like Nvidia is really serious about establishing themselves as an even bigger player than they are now - http://www.tgdaily.com/content/view/37478/135/
Besides talking about existing technology, NVISION will also mark the launch of several products. So far, our sources have not disclosed which ones we can expect. However, it appears that the technology focus will revolve around the GT200 GPU and APX2500 SoC processors.
We know that Jen-Hsun wants to beat Intel's official Nehalem announcement at IDF Fall, so we would expect Nvidia to be preparing something special.
NVISION 08 will take place in San Jose from August 25-27, following the Fall 2008 Intel Developer Forum with a one-week distance.
