if they had a realistic way to revoke OGL 1.0 material from that license they could do that. There is no realistic way of revoking OGL 1.0 material from that license as anyone who has already downloaded the material can reproduce and distribute it and if they do so they must provide for its use under the OGL 1.0 license or they have broken their license with WOTC.You say "...everyone who has [already] entered into the licence..." - what about those who have not yet entered into the licence, who as yet have no relations of any kind with WotC other than having purchased some of their products?
This is what I mean when I say get in before the lock - if by the time 1.1 comes out you're not already using 1.0 or 1.0a and they decide to revoke 1.0a (which would, I presume, drag 1.0 down with it) you would seem to be stuck with 1.1.
You seem to be under the assumption that they can remove SRD 5.1 from their websites and issue a statement on there that they are no longer licensing content under OGL 1.0. They can say that but The issue is that legally that would be a lie. Even if they did all that All you need to do is download the 5.1 SRD with the 1.0 OGL from anyone and you can distribute that under the 1.0 OGL so long as you continue to include the OGL 1.0 in your content and follow the other license requirements.
