If they aren't making RB3 DLC, Beatles DLC (for a game a year older than RB3) isn't likely even if Apple were to suddenly say "Go ahead".

The only likely instance of anything happening at this point would be some kind of Beatles RB3 export with what we already have. And again, that's not likely.

Can we get a lock so this doesn't get necroed again next year?
