There are five different islands in Episode 1; A winter island, a desert island with a seashell, an island with a giant tree and waterfalls under it, and a island that is essentially a giant cave. The final island is where the player fights the final boss, Doom Guardian. The Thousand Sunny can be explored, showing many of the rooms inside of it. In the Tankōbon version of One Piece manga, Oda drew a detailed interior design for Thousand Sunny including each piece of furniture and passage ways. From the current preview it seems Unlimited Cruise kept Oda's design down to exact detail down to the patterns on the walls and furniture.
The a7C camera crams in most of the a7 III's specifications, including 5-axis image stabilization, 10 fps shooting with autofocus, and oversampled 4K video into a body that's smaller in every dimension than the existing camera. A one-piece magnesium alloy structure helps keep the weight down (22% less than the a7 III, at 509g / 18oz). 1e1e36bf2d
