Wait until ... and ... come out.
Oh yeah, the PS3's motto - a neverending source of humor this gen. I wish the poor guys weren't waiting so much, bitterness is such a sad feeling ^ ^.
Anyways, both might be sjrpgs but both are the first decent whatever-rpg available for the console yet the sales were dismal. So far the ps3 has showed zero proof whatsoever to be able to support jrpgs better than the 360. Disgaea is a known franchise spanning both the ps2 and the psp coming from a reputable rpg-publisher yet its sales were comparable to a western-oriented new IP from a newly stablished developer (LO). Square-Enix is aware the ps3 is not the place to make money with jrpgs, that's why it's most important franchise is not showing up on it. Sooner or later you poor sobs are gonna come to terms with the fact the ps2-rpg legacy has not been inherited by the ps3.
