Don't forget Theatrhythm!
The music genre will come back in full force some day.
For now, I'm content to play rhythm platform games. Beat Trip Runner is one of my favorite games in the last 5 years. I got to play Runner 2 at PAX and it was awesome. Then there's the rhythm levels in Rayman Legends. Can't wait for that :-D
Or maybe some people just find these facts and figures interesting? You're right that it's common knowledge that Sony is in a rut, but does that mean we can't take a closer look at what's going wrong within the company? There might be no other purpose in that outside of reading about it for curiosity's sake.
And then there are people like Hatsune-Miku who apparently think Sony's financial struggles don't matter at all.
It's a damn shame. Great article with a lot of interesting little tidbits and insights into what's to come.
