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

first off, PS360 didnt take anything from WIi, you have to have had it for it to be taken away. Those games were never being developed for WIi in the first place. 360 was out before so alot of these games were being made with HDs in mind. But yes power did play a part
