This Wonderland speculation is interesting to me, in that I can see the sense in them going in this direction.
An area devoted to Wonderland could be as thick, well realized, and imagined and detailed as a Harry Potter land. There are lots of possibilities. I think that perhaps they might have to make a sequel of sorts, with a new original story in the "world" in order to flesh this out.
That having been said, I can't imagine that they haven't at least looked at the idea.
However, our trusted insiders have said nothing about this at all, and so I'm inclined to go with them, the track record is pretty solid.
This is my basis for saying, hmm, interesting, but I don't think we'll hear anything about it on Tuesday at all.
