I think they will. The process is going to be gradual, though. We might expect a plastic release of a TAG when a sectorial using it goes through a refresh. I guess that's when CB expects significant sales of the model, warranting investing in molds and enough copies of it from thier subcontractor doing the models (as unicool models are made outside of CB's own facility - contrary to metal and siocast ones). So, while I'd love to see, for example, a 3rd gen Maghariba sculpt (or even 2nd gen re-release in plastic), I wouldn't expect to see that earlier than when Haqq / RTF hits the spotlight.
It shouldnt. CB stated that all tags will be made in Unicool. That's plastic resin. Products that say thermoplastic are made in Siocast
My local online shop still has not deliverd my Adepticon ISS bundle - "waiting for new delivery date from CB" - whats up with this sets? They did not produce enough? Delivery should be end of april, now we have may 11th already! I know some people have it already - some even got it early, direct from CB - which makes the sitation more sad, because it looks like they give it away early but have not enough stock for delivery to the retialers.
It is worth mentioning that preview pages have been known to have wrong material information in the past.
