Nintendo home consoles haven't exactly been good consoles for RPG's since the N64 (which was absolutely abysmal on this aspect). So considering Xenoblade Chronicles X (which looks awesome as hell), Child of Light, the inevitability of a Paper Mario, Fire Emblem x SMT appearing someday and maaaaaybe a Crystal Chronicles someday, I'd say the Wii U is already in a confortable position =P
I wouldn't expect more than that though. Out of the big names, Dragon Quest is the one that would be most likely, but DQXI will either be a 3DS or a PS4 game (at least I'm fairly sure of it)
