From what I read he only stated that they were considering doing it. Haven't seen one bit where they confirm it's possible. I do hope they find a way though, without making us buy new stuff to make the AR work
They would just eliminate AR in the first place. It wash't really anything spectacular and since very few people like the Dream Eaters, I doubt they experimented with it much. They'd just cut it out and make it into a regular camera mode feature. Nothing of value would be lost.
As for the special DEs you'd get with the cards, any repackaged version would just have them automatically available in the game probably as rewards of some sort.
Everything else that was touch reliant in KH3D can be moved to button commands or to the touch pad.
