While this is true, both parties stand to make more money. If patches were made for GH3 and RB making either compatible with the other, then the GH3 people would make money cause people will still play GH without having to buy another guitar, gamers could battle on GH3, still buy DLC for GH3. And the people that have bought GH3 will feel better about buying RB. Oh, and for thos that say that they will lose money because of the price difference from not buying an additional guitar. Think about this, If everyone is using there second guitars from the other games to play. You can worry about producing a lower number, and with the problems that these have with failures and breaking, that means less to replace.
