I think the lessons learned from the original OGL were rather simple:
1. Having a OGL that allows for compatibility and free use of content for supplements that explicitly bear the WoTC role-playing brand is a very good thing. It helps the hobby and enables publishers to provide content for WoTC brands.
2. Having a OGL that allows for complete versions of new games to be developed needs to be carefully worded and observed. Paizo was a wonderful resource for D&D and still puts out awesome Pathfinder stuff. (I play both games) However, the existence of Pathfinder is a bad thing for D&D sales.
Expect a OGL that allows for point one, but doesn't allow another Paizo to sprout up when the edition gets revised. i'd also expect that at some point there's going to need to be a new edition of Pathfinder. When that happens they'll be going through the same stuff WoTC is going through now and tables may turn back towards D&D.
