most definite that sony will come out to be on top because kids are such brats that the parents will buy anything for their kids to shut them up.
most people will not buy ps3 quickly because of the high price. some people ask me sometimes what is the difference between the ps2 and the ps3, i tell them that it will be more powerful (graphics, and features this and that). i also mention that there is a possiblity that it might be around $400-$500 for it. then they give me a look that expresses, "what the fuck, are you crazy. that's too high."
it maybe that nintendo will have better sells because it's cheaper and will support multimedia features(playing movies, music, etc).
