Okay, so the Press Release is not currently a violation, but the moment they release the book, it becomes one. It looks to me that the very act of publishing the book under the license now creates a breach of the license. So, because of this press release there is now no legal authority for the publishing of this book.
How do you interpret this angle? Am I just off my rocker?
You are right that Valar has not released anything under the OGL yet, so it doesn't apply. The OGL says 'you agree not to indicate compatibility' not 'you must never have indicated compatibility in any prior release' - ie on my reading even if it were held to apply to works that did not themselves incorporate the OGL (which I don't think can ever be the case, but I'd need to study the OGL more & check US case law) it only affects post-contract works, not previously released works.
It's worth noting that the OGL creates disbenefits as well as benefits to those who agree to be bound by it, there are things I believe you can do under regular US trademark law that you arguably can't do under the OGL.
Eg under UK TM law and possibly under US law (unsure about the exact effects of the anti-dilution provisions) you can put 'this product is intended to be compatible with D&D rules but is not itself authorised or endorsed by WotC inc' on a work, which you probably can't do under the OGL.
(I had a long conversation with another law lecturer about UK trade mark law yesterday, still have it on the brain!)
