None or all of the above.
I'm considering getting both. However, when I think about it, the original reason why I choose to buy the Xbox and PS2 was because there were other games on those consoles that I wished to play. Now that I don't have time to play as many games there really isn't any point.
Both the PS3 and the Wii look awesome. I might sell my Xbox360 and buy the other two.
Or I could just get none of them. That's definitely another possibility.
