Was graphics power part of the reason the PS3/X360 took most top 3rd party games from the Wii?

It probably did have some influence but that's definitely not the major reason. 3rd party developers fled Wii because their traditional public massively shifted to PS360, that's why.

And yes it is likely to repeat with WiiU (considering what we know so far, it may well change after E3)
