with such a powerful system, i expected something as grand as ff12, then we get versus 13 that looks good on trailer but the game is duke nukem forever that will never come out. demon soul/ dark soul is good but i dont really consider that rpg. dragon dogma is action oriented, not really jrpg eitehr too
I would consider neither Souls games or DD to be JRPGs, but some people seem to think that because of the nationality of the developer.
JRPGs have taken a huge hit this generation because of how unprofitable they are and how much more expensive they are compared to much more profitable genres such as shooters. While you mention PS3 era, easily the best JRPG of the generation is Xenoblade Chronicles, which stands shoulder to shoulder with some of the greats in the genre. As for the PS3, many will say Ni no Kuni; although, the outdated, boring mechanics make it hard for me to call it an "epic JRPG", just a very good game.
