thats kind of what I'm planning to doi as I have all thee second generation consoles as well...
I have a feeling that the PS3 will whip the Xbox though. the hardware is better, there are more games releases,
and as far as Halo 3 coming out. who cares, when Halo 2 came out PS2 had a better tittle (San andreas)
and no doubt will have some awesome titles at their release.
IMHO Halo 2 wasn't even that good, it's boring. and practically the same as the first game with only a few minor improvements. (such as two guns)
certainly wasn't worth the money I spent on it...
Xbox is my prefered comsole however, (which is why I'm waiting for San andreas on the Xbox.)
there is nothing like killing people to your own CDs as in game music...
