I have a friend that works for Sony's Playstation wing, and heard some interesting facts that I can't really share yet. However, stuff I can since it's been kinda thrown out. The new controllers have an LCD panel where the Home button on the current controllers is located.This will give notifications and so fourth from the PSN. It also has built in PS Move functions, and a button that uploads video to your " space " on PSN. ( I believe the controllers are going to have a " capture " button on them, so you can record video from your game and upload it directly to PSN, not sure if they have conglomerations with youtube or not though. )
The hardware has already been announced, and it is looking pretty solid. Time goes quick, you kinda forget that the PS3 has been out now for 6 or so years, the longest time Sony has took a break from coming out with a system between all 3 console releases. I personally think the PS3 has tons of juice left in it to create great games, problem is developers are having a hell of a time coming out with anything new and exciting. Now the main reason to come out with upgrades is just for turning consoles into all around media devices.
