Why is there little to be gained? A big pokemon game on console would be fantastic and like others said amiibos could be used greatly.
No, I disagree with this completely. Keep the combat turn-based but incorporate movement into a little, like FF tactics or if they do go real time kind make it real time with pause like Baldur's Gate where you could use the gamepad to move pokemon around the battlefield.
There's little to be gained because there is little to gained. You're repeating the exact same stuff that comes up everytime someone suggests this. Graphics, big world, console. You're giving no thought in to the mechanics of these games nor their design. All this would do is make development costs skyrocket.
