Still haven't ever touched a Rock Band game. Still intending on getting Rock Band 3 whenever my financial and social life can support such a project. In a way it almost relieves me when a game stops updating, because it lets me go into it without a doubt about what it's going to be. Everything I could get is already there, so I can pick and choose without wondering if I should wait for more updates.
I just hope someone still even carries Rock Band 3 by the time I get around to it... Otherwise that will surely end up one of my greatest regrets in life. Just like never having gotten the chance to play Steel Battalion
