Julien Merceron, technology director of for Square Enix, recently stated the next KH game will likely use the Crystal Tools Engine. This means it will look more realistic and not like it usually does:
FFDream: We presume, of course that this technology will be put to use in future productions coming from Square Enix. Do you believe Tetsuya Nomura could perhaps make use of this technology in Kingdom Hearts III? Julien: It's already evident that we're using Luminous Engine on various franchises other than just Final Fantasy. However, Crystal Tools, as I was talking about earlier, is employed exclusively on Final Fantasy, only for now. Since the next Dragon Quest X uses Crystal Tools, as well as internal projects such as Kingdom Hearts which also utilize Crystal Tools, it's evident that Luminous Engine will cover a large spectrum of gaming franchises and I hope it will be taken advantage of by other teams, but we still have a lot of work to do.
Sometimes I think square Enix forgot America was in a recession the past few years as they keep releasing important, non filler games for EVERY GAME SYSTEM.
Like I do not have enough money to keep up with the Kingdom Hearts Series.
