I remember seeing on IMDb's page about "The Legend of Zelda: Twilight Princess" that 50 Cent is supposed to be the voice of Epona, Link's horse. It's not there anymore, but...
Oh, and Link's horse isn't gonna be named Epona in this one, I think.
And they don't mention anything about the use of the controller ports on the Revolution. Are those control ports for the actual remote hook-up like a wavebird, or are they for the GameCube controllers so you can play the SNES/N64/Cube games that they say you'd be able to?
I don't think Tarantino's role in "Pulp Fiction" exactly qualifies, as it's a long-enough role.
...oh, and http://en.wikipedia.org/wiki/Cameo_appearance.
A little off-topic, but I was in my stats class yesterday, and my prof was comparing stats to "making a piece of cake," and that it was easier than doing so.
