Square Enix released a D23 Expo trailer for Kingdom Hearts III and another trailer for Kingdom Hearts II.5 HD Remix.
The Kingdom Hearts III trailer shows off some early gameplay footage. Dual pistols, roller coaster, and pirate ship are all new additions that the trailer spotlights.
The Kingdom Hears II.5 HD Remix contains Kingdom Hearts II Final Mix, Kingdom Hearts Birth By Sleep Final Mix, and the cinematics of Kingdom Hearts Re:coded all remastered in HD.
It is still uncertain whether Kingdom Hearts Dream Drop Distance (also known as Kingdom Hearts 3D) will get a remaster treatment or not.
