[UPDATE] Kotaku has updated the article, Superbot is not shutting down, simply beginning the next chapter. Santa Monica to take over
I don't know how much stock you put into Kotaku, I dont put much but Sony is set to handle all future DLC for allstars, and super bot may shut down.
EDIT: Personally, we shouldn't expect much of a change, even if SuperBot does close. Sony is fully capable of running this game and providing us with DLC and patches. After MediaMolecule stopped working on LBP, another company took over all patches and DLC, and did a great job. I'm not worried here.
