Is there going to be more worlds from wiz?

Jun 18, 2013
I was wondering if any of the other worlds from wiz are going to be added? I'm only in valencia right now so the only other wiz worlds i know of are dragonspyre ( well the sky way at least), marleybone, and mooshu.
I think it would be so cool for avalon or celestia to be added in, " well just because those are my favorite wiz worlds XD".
