EDIT: The only problem with this is that, for some reason I remember him saying he'd LIKE it to be on home consoles, rather than it is specifically being made for home consoles. But, still.
I still think that SE won't let the game be a home console exclusive (PS4 or PS4/PS3), even if Horii wants that.
They're pushing the PS4 because they know that FF XV will sell (way) better in the West. The same isn't happening with DQ XI
But I hope i'm wrong. Play an (offline) DQ again in a big screen would be incredible
