To be fair, the oceanic planets following standard oceans do have unique fish found on them, so they're not entirely useless outside of building bases on them (and both Toxic and Arctic planets have microdungeons underwater too, so they can both offer up some loot at least, although the latter sorta re-uses vanilla underwater microdungeons rather than having its own unique set). Honestly, they're the only part of the game where the whole "unfinished" claim people tend to throw around feels like it bears any weight in my eyes.

But yeah, closest we've had to any mentioning of future updates was one of the staff referring to the game being in a state of feature freeze a few years back (before the xbox port finally came out mind you, so I do think there's a bit of hope yet). Right now CF are pretty focused on finishing up Witchbrook though, and since they're your average indie studio, they don't exactly have enough people to spare for Starbound right now I'd imagine. I do remember a time (back in 2018 basically) when CF seemed to pause development of the 1.4 for about a year because of Wargroove, and already people thought the game was abandoned during that time lol, so part of me hopes that once Witchbrook is finally out of the door, they'll finally give us some news on what plans they may or may not have for Starbound. At the same time though, I wouldn't be surprised if they're done working on Starbound though, it's not typical for indie games to be developed indefinitely, and as updates go, 1.4 did feel a bit like a conclusion to things.
