Optimism: We've got to wait until December for Rock Band 3. That's all that's mentioned. The others will arrive in a preceding update.
Super optimism: The other tracks will, over the course of a while, be released as DLC wherever possible. Similar to Blitz, we'll see packs come out with two new songs and one export, or something similar. Foo Fighters will get a 4-pack. One song will be new. It'll be more expensive, sure, but they've been out for plenty of time as a pack, so it's better than nothing.
Super duper optimism: AC/DC aren't dicks about licensing individual tracks anymore. Let There Be Rock will be available as DLC, as will the whole Live at Donington pack.
I feel like if the "super optimism" part is true, we'd find out in a week or two, because there's so many songs/artists between the 4 discs that they'd start that process as soon as possible.
