I would personally recommend the 360, if you choosing for a safe bet. At this point in time, the 360 has matured wonderfully, with great variety of title. PS3 is still struggling with adding more games releases into its library, while Wii are for the niche market, although if the concept takes off, im not surprised if it does catches on.

But for at the time of the writing of this writing, the 360 looks like a safe bet.
