No mention of it because there is not going to be a preview of it before Tasha's as it will be official instead of UA. Adam has stated that. But I think they was close to releasing it anyways. But now they have a little more time to refine it. So don't look for it before Tasha's comes out. But I'm almost certain it will be done, and the options within it will be available here on Nov 17th.
they have already stated that the reason that there is no digital pre-order available yet is because wizards of the coast has not authorized it
