Just got a text from rockbandaide that says the pax east panels have been announced and that it's confirmed hmx is announcing a new title. So what does everyone think it is? Rock Band 4? A new kind of Rock Band? Dance Central 3? Or a new ip?
"Join Harmonix developers as they discuss and dissect ten years of beatmatch gameplay creation, tracking their long and glorious tradition of designing music rhythm games like Frequency and Amplitude right up to the first public reveal of a brand new title!"
Given the topic they're discussing, my bet is on rb4(or at least a rb style game).
