Is that a remake of a PS2 game, or a completely new one? I once played a Tensei game via PS2 emulator...suffice to say, it was "interesting". And hard as ass.
Seems like the 3DS is now slowly but certainly picking up some speed. New Castlevania, this, and who knows what else might come down the road. As a handheld, the 3DS certainly seems to be more interesting than the PS Vita.
