Hmm.
If they are going to stick to their guns, a press release defending their plans would be fairly easy to write. Plant a flag defending Wizbro's rights to its IP, talk up how the OGL 1.1 still allows extensive 3PP participation, etc. It's not like the furor will be lessened by waiting for more and more people to weigh in (various publishers, YouTubers, the EFF, Cory Doctrow, etc.) before declaring they're going full speed ahead.
On the other hand, if they're changing course, there's all sorts of people who have to sign off on the new plans and how to present the new plans, shuttling things between execs and legal and back.
On the gripping hand, of course, it could just be that there's an internal argument over which course to take, and all we're seeing is a delay before Wizbro declares that it's going to do everything in its power to kill the OGL 1.0a.
