LOL,
IF I was just joking about the "PS2 killing the Wii" in the title (I put "not sure" at the end ...)
I really think that PS2 and Wii are playing in the same category for 2 reasons :
THE PRICE and the high numbers of party games/casual game released on both consoles
If someone is not sure if he will or not buy the Wii, he will not be interested with a PS3 or a Xbox360 BUT he may be interested in a cheapy PS2.
PS2 is still the big money "seeder" of SonyCE and is still the best way to stop/counter/reduce/limit/modulate the Wii Storm
and NO, PS2 sales doesn't hurt the PS3 sales except for the 0.0001% of people that think
PS2 = PS3 - 400$ : I m sure people are not completely stupid
Time to Work !
