I can't say at the moment, I won't own a PS3 just because of all the BS that sony feeds their users. Its going to be between the 360 and Wii for me at least...
360 for me one day.
I prefer the lower price and it has excellent graphics.
I also prefer to support American companies as opposed to Japanese companies.
and I'm already used to the normal xbox... doesnt seem like much of a contrast switching consols, but you kind of get used to a certain one. Creature of habbit
