Can a PS2 handle all the games that are / can be developed on a Wii?

As such, are there / will there be games that, even ignoring motion sensing of the Wii remote, that can be done on the Wii, but are too much for the PS2 to handle?

If you are talking about the pure technical aspect, see: Super Mario Galaxy and Super Smash Bros. Brawl.
