Not really, TTK is going to be a sizable DLC, I really feel it will at least take a few weeks to complete everything on all 3 characters and will keep me busy in till Halo 5 comes out. Did you watch the HoW set of streams, they pretty much did them in the same way. Only different is with TTK there is a lot more changes to the tower to go over then when they showed off the reef for HoW so the tower changes were put into one stream that was about an hr long.
