Guys, if you look at SCEWWS's past, the ONLY jrpg they've developed internally was the Legend of Dragoon for the ps1. Everything else was either 2nd party (Level 5 games) or 3rd party.
That being said, SCEJ is still being dead silent. SCE Japan Studio is like Nintendo EAD, just much smaller. They usually work on multiple games at a time. Last gen they produced three Ape Escapes, two Siren games, and a few others. This gen all we've seen is Siren: Blood Curse and Afrika, neither of which have been released almost two years into the ps3's life.
