Just got a quick email from Harmonix's PR letting us know that there will be no announcement for next week's Rock Band
DLC today. For whatever reason, they're going to have to wait until Monday.
Now don't go speculating about some huge DLC announcement. Any number of things could have prevented today's announcement. This doesn't necessarily mean that they just haven't yet gotten clearance to announce Reprise Records' entire catalog of music for next Tuesday. But you never know. We have been waiting patiently for those albums, haven't we?
(No, I don't know anything about it.)
