MR were taken over by Corgi earlier this year.I am of the opinion that the new company didnt want to renew the license as they realised that MR had pretty much run out of room for SW pieces to make.All the sabers had been made,with the possible exception of some of the anonymous Jedi council sabers,mostly all the blasters had been made,pretty much all the important helmets had been made (except for the TIE pilot and Royal guard) and other than some pieces like a Vader TIE advanced or a Star Destroyer pretty much all the studio scale models had been made.MR had simply gotten everything they could from Star Wars.I believe it was Corgi,rather than LFL,that drove the decision not to renew the license.Some of the MR stuff this year has been poor.I dont think the trooper lid was the disaster that has been made out.Sure it was idealised but they need to cater to a larger market and not just uber-accuracy colectors.However quality did noticeably slip with things like the paint job on the Fett blaster which was a total disgrace.
Personally I would have liked a Dooku FX as that would have been a really nice FX saber.The problem being now,of course,is that some new company will get the license and just start rehashing all the same old pieces that everyone already has.
