I have the Wii60 combo (Wii+Xbox 360). This is cheaper then just a PS3.. That was the selling point for me.
Hell the lowend 360 (Arcade modell,256mb memcard,HDMI) is even cheaper then the Wii now.
I think i will buy a PS3 in the future if the price goes down and there is some games that i want to play. Right now there isnt a single PS3 exclusive game that i want to play
and i will never buy a PS3 if i cant get one that plays PS2 games. (never owned a PS2 and would like to play some of the games on that console.. But i dont want YET another console under my TV)
