It might be an odd suggestion to make, especially so far past the systems expiration date, but if you want to glut yourself with good jrpgs, look into picking up a cheap PSP and a set of composite cables. Hook the thing up to your tv, hit the couch and you can do horrible things to your gaming backlog.
The remastered Tactics Ogre, the first Legend of Heroes Trilogy (not as good as the Trails series, but still not bad), Riviera, Brave Story, couple Tales games, Valkyria Chronicles 2 (and 3 if you're not averse to english patches and hacking your system), Jeanne d'Arc, too many to name. It likely will never become your go-to source for jrpgs but there's plenty here to fill in the gap between major new rpg releases.
