ok so i'm going to try keeping on top of the KH 3 knews that's going to be coming out and the reason i'm making this thread right now is simple because of this video.
from what i hear this does not pertain to any sort of possible release anytime soon.
tetsuya nomura stated himself that "the staff is not satisfied with the current state the game is in and will take more time to develop it"
he also states that the ship and rollercoaster are adapted from the flowmotion system and they will change depending on the world iirc. If i heard correctly the system is called freeflow or something along those lines (i'll check it after i've posted this)
and finally you might notice at one point sora starts fighting heartless with guns this is part of the new keyblade transformations that we will be getting (confirmed by nomura). This will most likely take over the drives form bar that we used to know however this is not clear and is pure speculation by myself.
so if there's anything else you guys notice let me know as i would love to sit here and disect the fuck out of this gameplay oh and also nomura has stated that all gameplay shown is still subject to change in some way as it is still very much an alpha they only showed this gameplay trailer to appease the fans that sat there at their computers crying and screaming like idiots. (not his exact words but i feel it needed to be said :P )
