I dont think We'll see an Xbox 720 in 2010

[DirtyP2002]

I think MS will announce a new console at March / April 2011 and launch it September / October 2011. The 360 would be almost 6 years old. This is more than enough for a console. 5-6 years is perfect for a piece of hardware. But I bet the PS3 will not last for 10 years. If MS does like I predict and sony keeps its promise (would be the first one this generation) the next xbox (and likely the wii2, too.) would be released 5 years before the PS4. Sony would miss an entire Generation and the big brand "Playstation" would have been gone.
