To me, the next Gen does not start until the PS3 and nextbox arrive because gens are defined by me mostly by graphical leaps. And I do not believe the Wii U will be much more powerful than the current gen or it will be about the same.
I am thinking of moving towards a PC and only one next Gen console that would probably be of the PlayStation brand as the did the best for me gaming wise this gen by far. MS got a lot of early exclusives many of which later turned out to be only timed. They just do not have enough exclusives I like yet to justify it being my first choice, waiting to see.
But who cares I prefer to be open minded about many things beyond gaming. Trying new things is fun.
