Really hope this doesn't affect OGL 1.0a the way some people are saying it will, particularly regarding non-DnD systems. I've been working on a project for several years that's based on the Cepheus Engine RPG system which was published under OGL 1.0a (as it's based on the Traveller SRD which was also used OGL 1.0a), which requires me to publish under that license as well. Now that's all up in the air, what happens if OGL 1.0a becomes 'unauthorized' in this case? If this ends up killing Cepheus I will have wasted thousands of hours of my time.
The Traveller SRD is (c) Mongoose Publishing. It seems implausible that the OGL 1.0a could be construed to give Hasbro any control over intellectual property that isn't derived from their own. It should be possible for the rights owners to simply relicense Traveller, Fudge, etc. It's Paizo that is in a difficult spot, because their SRD still explicitly references material from Hasbro products.
