Sequels To Updates

Currently, the most recent update is the Aquatic Update. It added much-needed content to oceans. I believe the developers should continue to produce game-changing theme updates like this. I also believe these themes should be revisited.

So maybe, for example, a couple years in the future, the developers could make The Aquatic Update 2 (don't call it that though give a new name that suits the theme like The Marine Update). 

Sequels could contain ideas that may not have made into the aquatic update but the idea has been developed or redesigned to be added. Plus any interesting ideas made by the community
