This came to me over coffee this morning. I feel that all of the GH2 DLC that one purchases of XBL should, in time, be useable with GH3. I'm not sure how coding and all that nonsense works so I don't know if it's entirely feasible. But I do know that the phantom pains where the arm and leg that I severed to pay for said DLC would be eased slightly if I were to say, be able to play those songs on GH3 at some point in the future without having to repurchase them. Just a thought.
