My guess is that WotC is going to just use the existing studio as a starting point on which to build up a new studio including with some well-known people. The studio currently only has 55 employees, nowhere near enough to make a true AAA game. I expect it will be expanding immensely over the next few months. WotC has long wanted an in-house videogame studio to make D&D games so that it could avoid the ugly and unhappy situation they had with Atari for many years. I guess they finally have that with this acquisition.
