If your looking for a good JRPG on the PS3 you're gonna have to wait until Tales of Vesperia is ported.
Fortunately there are plenty of good JRPGs on the PS2 if you either have one or your PS3 is backwards compatible. Shin Megami Tensei: Persona 3 and Persona 4 are, in my opinion, the closest things to gaming perfection in the world today so definitely give them a shot. Tales of the Abyss is also a great choice as well, mainly because of its fun battle system and the grade shop.
PSN has Final Fantasy VII so if none of the above options appeal to you then check it out. I wouldn't say it's the best Final Fantasy but it's definitely worth what you'll pay for it.
