I don't think there are any plans.

SE's working on the basis of catering to the mass populace of the everyday gamer. So they release regular content but at the same time sprinkle just enough to keep some niche groups interested. Take ultimate baha for example. Its one of the "cherry on top" features that came out on top of regular content.

Its clear their collective motto is to playing it safe and the thing is, it works. People complain about staleness but its not a majority.
