I seem to recall Harmonix claiming that they would never need to release a Rockband 2 and that all future song releases would be coming in the form of DLC. I knew this was a lie from the begining and was only marketing spin to get people to pay the $170.
I still hate them for fucking up the Wii version so bad. It would not have been hard to make it from the ground up instead of porting it. What makes me more mad is that they tried to blame their laziness on Activision. If they had used the wii-remote standard all instruments would be compatible with GH4 (except maybe the drums) something they also claimed they wanted to see happen.
What a bunch of lying assholes. As a result I'll never buy one of their games.
