In Japan, the sequel will be titled Moero! Nekketsu Rhythm Tamashii Osu! Tatakae! Ouendan 2 (the original was just Osu! Tatakae! Ouendan). The first part of the title translates to "Burn! Hot Blooded Rhythm Soul!". Now we're really excited! Aside from the promise of multiplayer support for up to 4 players, details on the sequel have yet to be made public.
