Nope, not for MS/Sony I think. The Wii is dropping a lot so for Nintendo yes, 2012 is time for next gen (and funnily enough here comes the Wii U) but for MS/Sony sales aren't too horrible really. Also, they need to consider the global picture - there is a balance between reacting fast to US but reacting too fast globally.
Personally I still think 2012 for another decent 360 year with Halo 4 then nextbox Q3 or Q4 2013.
For Sony I think either Q4 2013 or Q2 2014.
Try to be reasonable... its easier than you think...
