Demo (today; free; currently only available to Gold Members) - Green Day: Rock Band - includes two songs: Welcome To Paradise and Boulevard Of Broken Dreams - When you exit the demo, you're treated to the revelation that Rock Band 3 (which is coming this fall) will include keyboards as a playable instrument
Also, the Rock Band 3 keyboard I mentioned earlier in this thread may, in fact, be a keytar. That same article also claims there will be a "pro" mode, which "will require proper technique, and may lead to actual skills on guitars and bass. How this will work isn't known, but it's possible Mad Catz may create a product that more closely mimics an actual guitar."
Yeah, Battlefield 1943 is great. Shatter is freaking AWESOME if you like those types of games. Super Stardust HD is all kinds of fun, and even has a multiplayer add-on. Siren is a great, albeit expensive, download.
