I still have yet to see dates for these myself. I think most of Wave 1 just reships as variants. Hopefully we will hear something more concrete from DST or the vendors soon.
My order still has yet to be filled, which has me a little worried...
BTW as for the rumored variants I think those four are coming out for sure, I thought I had also heard rumors of General O'Neill in his blue fatigues, but I can't confirm that.
