What should I get, PS3 or 360? (From a Wii owner)

[Hawk]

I went with Wii60 and am very happy with my purchase. I am hoping to eventually get PS3 though. But it really is the games that matter. Maybe people should name their top 4 or 5 games they recommend for the console they recommend, and you decide which has the more attractive games to you.

On my 360, the games I most enjoy and recommend would be:
Bioshock
Dead Rising
Gears of War
Halo 3

I also got Eternal Sonata, but haven't played it yet. But it looks awesome
