A few years to go yet, MS have just spent $500 million on marketing alone just for kinect, they'll want to make that a big part of future Xboxs if it goes well. They'll need a year or so at least to be able to judge the market and show they can do core gaming with motion sensing. Sony not so much riding with the move, but will still like to see in doing well for the same reason as MS, and also PSP2 supposed to be out this time next year cant see them announcing PS4 in that time frame. I would think that 2012 we will see new info on next consoles from MS/Sony with a 2013 release date. Nintendo i guess are starting the "next gen" for handhelds with the 3DS coming out in March 2011, but as Wii sales are dropping off while the other consoles are gaining market share Wii 2 probably will be announced late next year for a 2012 release.
