I have zero interest in anything prequel-related, and one would have to assume that HT feels the same way. With The Force Awakens and now Rogue One offering up a host of new characters that appear to have resonated across pop culture generally, I'd imagine that prequel interest will be confined to hardcore fans. The OT vibe is the focus of the moment, and I'm not sure Disney/Lucasfilm would care to license anything that would undercut their forward, albeit vintage, focus. With a new SW film every year, HT will have its hands full catering to demand for new characters, and coordinating their releases to achieve maximum synergy with each new promotional cycle.
Besides the OT characters in TFA all the "new" characters are garbage. Lucas can't direct but he can create Characters. I'm in for Hot Toys Prequel figures. Yes I'll even buy a Pod Racer!!!!
