Portal 2 Trailer: But Will There Be Cake This Time?

I didn't actually play the first Portal game, but I did watch Fernando go through the trials and tribulations in the name of science and cake only to discover that the cake was a lie.  I still have nightmares about GLaDOS and the trailer for Portal 2 is not helping matters.  Will we ever be free?

You can learn more about Portal 2 here.  I have no idea how it won awards at this year's E3 when it doesn't come out until next year, but then again, the world of videogame insiders isn't really in my wheelhouse.  And here's the credits from the original Portal.
