Minecraft won't stick with its look forever, but it looks like it's going to take some time before it gets an overhaul. Mojang just announced that it won't release the Super Duper Graphics Pack visual redesign. After two years of delays, the developer decided that it was "too technically demanding" to implement. And the company wasn't "happy" with the upgrade's performance across platforms. Instead of providing inconsistent quality across platforms, Mojang decided to just shut down the project.
The promise was to enable 4K on the Xbox One X as well as introduce more sophisticated visuals effects for areas like the atmosphere, highlights, and water. It doesn't mean that Minecraft won't get a redesign, though. Mojang is still "looking into other ways" to give Minecraft a new look. And that it has news on optimizing the constructive games on different platforms "very soon."
