Well, in the new to HTS section there are now a bunch of figures listed as OOS or Coming Soon. The figures are from the Thanos and Mystique waves. I would expect these to go up for sale, unless I missed it already, within the next day or so.
Anyway, hopefully this is a good sign that HTS will once again become a viable option for obtaining MU figures.
update: Mystique wave now mostly in stock a few still "Coming Soon" - Thanos wave still "Coming Soon"
