Regardless of what future license they apply to content, what they need to do first is release an OGL 1.0b which contains "irrevocable" and ensure it is applied to all current 1.0a content as this was the original intention of the OGL [1]. Then they can release any 1.1 they want.
> 7. Can't Wizards of the Coast change the License in a way that I wouldn't like?
> Yes, it could. However, the License already defines what will happen to content that has been previously distributed using an earlier version, in Section 9. As a result, even if Wizards made a change you disagreed with, you could continue to use an earlier, acceptable version at your option. In other words, there's no reason for Wizards to ever make a change that the community of people using the Open Gaming License would object to, because the community would just ignore the change anyway.
where section 9 of OGL 1.0a says:
> 9. Updating the License: Wizards or its designated Agents may publish updated versions of this License. You may use any authorized version of this License to copy, modify and distribute any Open Game Content originally distributed under any version of this License.
