Famitsu managed to get an interview with Nomura, during which a lot of new info was revealed. A website managed to write a summary of the interview.

re:COM

1. There will be separate areas for the battles, just like the GBA version.
2. The Bonus experience and leveling style from re:COM is similar to that of the game boy advance.
3. The stock technique is back.
4. You can have an additional reaction command, which will depend on the technique used.
5. An example being that if you use Sonic Rave, you will be able to use another technique with it.

KHIIFM+

1. Similar clothes from the first game, that's shown in the Jump Festa trailer, is Sora's new form.
2. There is no connection to the Org coat Mushrooms, and the Organization XIII, they are only mimicking them.
3. Because the voice acting of the XIII Order in Kingdom Hearts II was so wonderful, he plans to top that with re:COM
4. In re:COM the map gimmick, things like the Guillotine is put on the map, in Halloween Town.
5. The character in the secret ending of KHII, who was also shown in the Jump Festa trailer is New, not Sora or Roxas, however he does have relations to a character (Who's name he doesn't say)
6. The scans and the Jump Festa that show's Zexion's weapon was just him copying it, because Zexion has the ability of "Phantom/Shadow" however Zexion DOES have a real weapon.
7. In re:COM the reaction command with stocks, needs to be timed correctly in order for it to work.
8. He plans to continue the KH series, and plans for a big announcement next year. He has two or more projects in store for, but he wouldn't give out any detail about any of them.
9. They are soon planning for the Kingdom hearts FM+ Release date's announcement. Though they are not sure when to announce it.
