Well, we already knew that the Wii was weak compared to the other consoles. In Shigeru Miyamoto’s E3 2009 roundtable, the designer had a candid moment when discussing Wii hardware. Some might say he was a little too honest.
When talking about the New Super Mario Bros. Wii, Miyamoto said that since the game features four-player multiplayer and multiple camera views, the Wii’s processor is already being taxed pretty hard. Sounds like the Wii processor is already starting to show some limitations. Miyamoto also said that, “I would like to use Wii Speak more, but [in SMB] the Wii processor is already being taxed.”
