Okay, here's something Scott probably can't answer until Monday:
What if I decided to write a new 4e-GSL-compatible product, but wanted to include
someone else's OGL content? For instance, an artifact from a sourcebook published under the OGL, rewritten for 4e stats.
My current understanding is that this is not possible, as we can't mix OGL & GSL in the same product. Which basically means unless the publisher themselves update the product to use the GSL, I cannot use that material at all in my own product.
That would be my biggest disappointment in this development: all that old content that's ripe for mining ideas here and there gets cordoned off into "OGL only" land. Still, it's understandable why that would be the case.
Also, that leaves us with the one question not fully clarified yet: is a publisher required to publish GSL material only, or can they publish separate OGL & GSL content (ie, not the same product at the same time)? For example, I could publish a "Dungeon Snacks" OGL supplement and a "Dungeon Weapons" GSL supplement at the same time as separate products, but not publish a "Dungeon Weapons" OGL at the same time my GSL version of the product is on the market?
I think getting those two questions clarified would do a lot to settle this thread down a bit.
