Alright, I'm going to attempt to answer all of the questions brought up so far in this thread:
1. We will have several hundred DLC to choose from at this year's con on a machine provided by the crew that brought RB to us last year.
2. There will be a moderated tourney with a final round hosted in Live Events.
3. Free Play Rock Band is available throughout the convention except for the times that the tourney is running.
4. Rock Band will be hosted in a section of Console Gaming as it was last year (PLEASE NOTE: We've been moved to the basement of the executive tower this year)
Hopefully this clears up any confusion you may have had
