Future Rock Band DLC to be incompatible with Rock Band 1 and 2

Rock Band 3's a definite must-buy.

No, we mean that. You must buy it if you want to keep downloading Rock Band DLC.

Speaking with Joystiq, a Harmonix representative explained that Rock Band DLC released after October 26, 2010 - a date that, for those who've recently awoken from a coma, has already passed - won't make sweet, sweet music with RB1 or 2 "due to the new authoring standards, inclusion of new instruments, new lighting / venue cues, etc."

If it's any consolation, the colossal mountain of music available before that date is unaffected by the new policy.

Also, Rock Band 3 is apparently kind of decent or whatever - if the words "greatest music game of all time" mean anything to you. They probably don't. Also, no pig men. That's a pretty big deal-breaker for us.
