Things on the music game front have been surprisingly quiet. We know that Harmonix is working on Green Day: Rock Band, that much is certain. But that's pretty much it. Pretty odd when you consider how many upcoming music games we already knew about this time last year. (Could it be that we've reached the point of saturation? We have some thoughts on this we'll share with you soon.) Rumors about two more music games are swirling; one of them is confirmed, while the other isn't as substantial.
