E3 is a week away! Who else is going, and how many of the days are you going for?

Do you think a demo of the expansion will be available? Do you think a playable demo will be there? Will more than the two hinted at new classes be spoiled? I'm pretty hyped! E3 always has games that aren't coming out until the following year / future, so it's highly likely the expansion will be at least be mentioned/shown.
