Well, no. For one thing, OGL 1.1 has not officially been released yet.
For another, one of the main issues under dispute is that, unless the license you agreed to says terms may be changed, then you can't generally unilaterally change them, much less change people to a completely new license without their knowingly establishing a new agreement.
And, that's an issue. For example, we here are all part of a discussion. But someone who doesn't haunt message boards could come across a PDF of the SRD, with its associated license, and in good faith follow the terms and make their own thing, and be in complete compliance with v1.0a.
So, how does WotC have the right to call them to task and financial burden for that, when they've never even heard of OGL v1.1? There's literally tens of thousands of copies of the old license floating out there, and WotC can't edit them to update people that the license they carry is no longer useable - the license specifically says the thing is perpetual, and has no terms of termination other than breaking terms explicitly in the license.
