me personally, i think i will continue to look at my PC as the true "next gen" gaming system, and will maybe pick up a Wii a year from now if i happen across a great deal. and that will be for the same reason i got the gamecube (long after it was released): great, fun gaming for a group at a great deal.
the only thing i would probably ever want the PS for is gran turismo, but again, that just goes back to my PC, which is not lacking in excellent driving simulators.
