They said PS4 version will run on UE4, so different games (or different styles and possible different gameplay for same story).
I personally don't get that, a lot of time spent developing so many different products. They should just focus on the 3DS game or the PS4 game and it make the best possible. Then develop a PS4 game or 3DS game after.
I'm slightly worried by the amount of active developments SE has going right now, between all this DQ stuff and all the E3 announcements.
Well...potentially best of both worlds. Users that prefer DQ portable and those who have wanted the return to HD - both satisfied. Square-Enix gets to appeal to the already large DQ userbase on 3DS but Yuji Horii gets to make that (possibly) definitive version on PS4, while grooming that platform with more DQ titles before release. Everyone wins, I guess.
