I question how long Hasbro is willing to let D&D go without releasing any real product... unless someone has once again convinced them that maybe THIS time D&D will become a multi-billion dollar franchise on the level of MtG.
By the look of things, it would seem the plan is to turn D&D into a long-tail product. Instead of trying to make a ton of money every month, it will make a steady profit for many years.
The re-release of older materials hints to this, and may be a major profit source over the next couple years as D&D Next is being developed.
