Rock Band 2's features

I wasn't able to go to the demo EA and MTV did for "Rock Band 2" a couple of weeks ago, as I was on vacation (poor me). So you'll have to wait until next week to get my opinion of how it all works in practice.

But for those who are curious, I can share all the key features of the game that are different and, hopefully, better than the original "Rock Band." There doesn't seem to be anything revolutionary here. Basically, it's "Rock Band 1" with most of players' complaints fixed.

-80-plus tracks on the disc, including Foo Fighters' "Everlong," Red Hot Chili Peppers' "Give It Away," Journey's "Any Way You Want It," and The Who's "Pinball Wizard"

-all previously downloaded songs are compatible

-all instruments are wireless

-mini-campaigns organized by instrument, artist, album, or genre

-each character can play any instrument (inability to do so was a MAJOR pain in the original "Rock Band")

-Band World Tour can now be done online

-Can switch up instruments and even lose the "band leader" during the tour

-Battle of the Bands, either versus friends' bands or in online contests organized by Harmonix
