I would suggest that WotC invest in a PDF store and on-line tools that help with running the adventures (printable maps and tokens, VTT integration, monster summaries, maybe print-on-demand). That way third parties can go through the effort of writing the adventures, and WotC can take a cut of material sold through their store.

Great idea. The iTunes model. Buy a D&D book and you buy into the WotC ecosystem.
Unfortunately, the example they set with DDI and the supposed virtual tabletop that never materialized makes me cynical about their ability to do this. Might be their best hope at succeeding with 5E, though.
