Next Gen Coming 2010?

Analyst Evan Wilson has recently predicted that the next cycle of game consoles will begin in 2010. He says Nintendo will follow with Microsoft releasing later that year. He has no word on the PS4 which will surely take much longer to come out.d
Personally, I don't know if I believe this too much. So I believe the Nintendo part. Its inevitable; especially since their console is the least advanced of the three. I think Microsoft will be out in 2011 though. I don't know why I think this, I just do. It makes no sense to release a new console, if people are still buying the old one and unless somehow Sony manages to take over the market, I think people will be buying tons of 360s in 2010. We'll see though.
