Is it possible for the Wii to have games like Bioshock, MSG 4, and GTA 4?

For everyone that is talking about Wii's RAM... it uses an UMA just like the 360, therefore any part of the RAM, be it the A or the B, can be used for anything the developer wants. And the OS runs on the 512MB of internal flash memory, not on the RAM.

Ok, you can continue *gets popcorn and watches*

What? Is that flash memory fast enough to execute code directly from it? I'd think the code gets copied to RAM before execution (perhaps overlaid to save memory).
