The man who brought us Pong and founded Atari, Nolan Bushnell, had considerable praise for Revolution's controller as well as Nintendo's overall strategy at the Digital Entertainment Conference 2005.
"The 3D controller that Nintendo is on to is a very good idea," [Bushnell] says. "If you look at todays controller with triangles, Xs, squares and circles, its scary. Its like a keyboard. People are interface phobic."
Other highlights from Bushnell's commentary (though admittedly nothing else on Nintendo) can be found in Kotaku's coverage.
