Medicom NEVER lost the Star Wars licence. They have stopped making any kind of Kubricks. Most likely because bearbricks are cheaper as they're just repaints.
Yeah, they've still been pumping out the SW be@rbricks in the last two years, the last one was the Jango/Boba 2-pack if I recall, and maybe even RAH's.
I'm sure be@rbricks are much cheaper to produce than kubs and in that case I'd happily take a bunch of repaint kubricks from Medicom if that was the choice between something or nothing. They could do a box set of x-wing pilots and just reprint the face and helmet.
But maybe it's not down to cost. Pure conjecture, maybe the DX line, which tried to take things in a different direction, didn't do so well.
