I would think the licensing for Melty Blood would kill the chances of it coming here, but then again, I think that'd be the case with Hokuto no Ken, as well... and Markman previously said that Sega didn't want to do it. Perhaps that's changed in these "dump whatever shit you want on the PS2" days, but I dunno...
Maybe it's Garou for PS2.
Or the Spectral Force Fighter
Or Garouden Break Blow
Or maybe it's Guilty Gear Slash for the PS2.
The mind is being boggled at this time.
