I'm not Sony extremist, I think is hard for PS3 to reach Wii, but its the only one that still stand a chance. It could do it, deppending how many years Sony support it and the effect that might have the next price cut. Sony's systems are well known by its legs, even PSP has been pulling decente numbers.
If I have to say right now what I think. No, its not gonna catch the Wii, but its gonna be damn close.
