Tough one, if you did not have ps3 you should of course get 360. But when you have ps3.. could be that wii is better for you. That is if you find nintendo-franchises even a bit interesting. :p

Wait until after E3, compare each platform's titles and benefits+ negatives. Then you can make a decision.

Since you have a PS3 go with the Wii, unless there is a game for the 360 u must have but then again there are some really great must haves for the Wii and plus if yuu buy the Wii you can buy up to three games.

I would wait until E3.

I own both a Wii and a 360.

I prefer the Wii.

keep saving and get both
