I hope the one on the Wii U is much better, although I wouldn't bet on it. I'd still like to play this game, even if it is just to fire it up and run through pretty environments to do cheesy MMO quests. I've done a bit of that in Dragon Age Inquisition recently and, I dunno, I just find an RPG that's easy to slip into like that pretty relaxing.
Atlus seems to be the one to look to these days for great JRPG's. SMT IV and Persona both have some pretty great mechanics and Etrian Odyssey does a pretty great job of reviving Wizardry-esque dungeon crawlers.
I feel like what the genre needs, more than anything, is just a really big, popular, extremely well-made game on consoles and maybe PC. Persona 5 might be that game. I don't think FFXV will be, that series just needs a complete refresh - drop everything from the older games and make something from scratch that looks new and different. I think an SMT game - that is, a game like Nocturne or SMT IV - could be pretty successful, given the popularity of the grim aesthetics, difficulty, and mechanical focus of the Souls games.
