4Gamer recently conducted an interview with Japanese Game Developers to discuss their thoughts on 2014, as well as the future of their game series. Kingdom Hearts Co-Director Tai Yasue was one of these developers. He spoke about Kingdom Hearts 3, noting Keyblade Transformations (much like the Starlight transformation from the D23 Trailer) and Attractions. He also comments on the change to the Unreal Engine 4, stating that the team structure has been established and development is now moving forward. It's worth noting he mentions the new shader, the Kingdom Shader, that was talked about by Tetsuya Nomura back at E3 2013.

“Now that we’ve worked out Unreal Engine 4 as our development environment, as well as the general structure of the team and fresh new look for the game and its accompanying shader, development of Kingdom Hearts III is moving forward as we now focus on making things like new Attractions and Keyblade transformations. We’re hoping to be able to show our fans the fruits of these labors step by step during 2015, so stay on the lookout for more information!”
