What? Oh, they're still selling it, but the stream's over.
Also I don't know, they said they'd work more on the games afterwards if they liked the projects enough.
Oxeye still hasn't released a single build, so they're certainly not done yet(way to slow :V), and Mojang has released their source code, meaning they're probably leaving it to the fans to work on. I still haven't even downloaded them yet, though.
