I think Symphonia PS2 has a decent chance of releasing here next year. It's doing very well on GameCube and the script's done... seems like a good opportunity. Hopefully strong western sales of Symphonia GC are good enough to greenlight the sequel (Legendia) too a la Xenosaga.
People hoping for Rebirth (or worse Destiny II) to come over need to face things and realize neither has a shot though. 2D console RPGs are just too niche for Namco Hometek consioering the localization effort demanded, it won't ever happen. If you want another console Tales this gen, better start hoping Legendia actually exists...
