The magazine appearances are not stopping! Most recently, the December 21, 2012 issue of V Jump has contained an article on Kingdom Hearts -HD 1.5 ReMIX-. Scans of this article have appeared online, thanks to bKvEBVAvUq for the tip, and these can be seen below, in our gallery.
One thing mentioned is that there are 14 worlds in the Kingdom Hearts Final Mix portion of the game. This strongly suggests that Deep Jungle remains in the game (which some people have been worrying about due to Disney's copyright issues), as there would be no way to come up with a list of 14 worlds without including it.
Interestingly, the screenshot of Sora fighting Sephiroth shows a fourth command slot, in addition to the reaction command that replaces the fourth slot. The text in the fourth slot says "Summons", so, it seems like Summons will receive their own slot in the menu in this game.
