The only thing that's dousing my spirits on this announcement is that there won't be any keyboard parts in Rock Band 4. I'm not too choked up, as I never mastered that instrument like I did drums and guitar and vocals, but that's one of the biggest things to me: I wanted to learn it. it gave me something new and interesting to do so I could relive the times back on rock Band 1 when I was just learning drums. or Guitar Hero 1/2 when I first learned fake plastic guitar.
Hopefully they change their minds.
