I'd be happy with a wii successor that is a bit more powerful than the xbox 360 and ps3, and it should even remain relatively affordable by the time it comes out. However, I really don't think giving the wii 2 a simply boost in power is the solution. Third party studios are going to prefer putting their support behind the ps3 and 360 and I am concerned that the wii 2 will be left out of the fun again.
I just hope Sony don't release a console in 2012 just because Nintendo MAY release one, and I don't expect them too--the ps3 is doing great and has room for another price cut or two to help sustain sales while developers (of all kind) continue to pump out good quality games for the system. Also, I think Sony will definitely like to evaluate Nintendo's new console for the upcoming generation before putting out a console themselves.
