Is it available for wii?
Unfortunately no...it's only out for Xbox and I think they also have an older version for the computer.
We have a Playstation 3 and the Xbox360. I've got the PS3 hooked up to the big tv..we use it for Netflix as well as our blueray player for movies.
I wouldn't buy an Xbox. It's all a Microsoft racket. They advertise as being cheaper than the PS3 but by the time you purchase all the necessary equipment it comes out being more costly. Plus you haft a pay a yearly subscription to get online. Playstation is ready to go as is.
