Unfortunately, they are going the mainstream way, and currently more than 50 percent of desktop PC's are running onboard video. Intel is trying to deliver CPU capable of everything, and as they said, they are not planning to replace 1336 platform, this will still remain high-end performance standard. There will definitely be new architecture, able to render / fold / encode faster, but as we all know, this doesn't mean much in games. Maybe we'll all be surprised, but hey, isn't core i7 a good purchase at the moment?
Look at 775 platform, this was the one being replaced by 1156, and it is still capable of everything (gamewise)
For gaming PC, high-end GPU will still be the priority no. 1, and no integrated GPU will be in interest of a hardcore gamer, ever.
