The nice thing about an animated series is that they can always just pick it back up, or substantially reuse a lot of the material for something new without a lot of production headaches. Futurama was canceled by Fox, got picked up again years later by Comedy Central, and is getting new episodes on Hulu as we speak a decade after it last aired. I'm hopeful, as hinted in the article, that the current run is ending because of the premise stretching thin (perhaps also for dipshit studio business reasons) and not because they're done making animated Trek shows. While the show itself is great, I do appreciate that they might want to escape the lower decks concept and do something different.
