omg! That's awesome news!
Jubeat plus/Jukebeat 's local multiplayer isn't really for battles, it's just for comparing scores. But the neat thing about this is that the host can share their song data to the other device, even if they do not have the song! I thought that was pretty neat. Sad thing is that it's region locked. (ie Jubeat Plus can't join in Jukebeat game and vice versa.)
Reflec Beat plus being Universal is interesting. LANDSCAPE BEMANI GAME! Here's a screenshot of what it loooks like:
Realistically, it's pretty squished, but for restricting it to single-player only, it's not too bad. Very nice for those who wants their Rb fix.
