Two bits of news, the first of which is that there's a demo for Green Day: Rock Band available now on the Xbox LIVE Marketplace. I looked for it on my console and I couldn't find it, but you can queue it up online right here. It features full offline band play (including harmonies) and two songs, "Welcome to Paradise" and "Boulevard of Broken Dreams."

That's cool and all, but I suppose the bigger news bomb comes when you select "exit" on the game demo. You get a teaser for Rock Band 3, which displays all of the series' iconic instrument logos plus... a keyboard. Yeah, you're seeing that correctly -- it looks like keyboards will be a playable instrument in Rock Band 3.

How will they work? What will the peripheral look like? What songs will be playable using this fancy thing with the black and white keys!? If I knew anything, I wouldn't be able to tell you anyhow, so I should just shut up and let you guys do all of the speculating.

(Dear lord, Harmonix, please include Harold Faltermeyer's "Alex F" on the Rock Band 3 disc.)
