Well this is just sad. As I only collect SW, it's the end of MR products for me :cry
I consider myself lucky that I have just about all the MR products I want in my collection - and that with the Vader ROTJ saber release they finished all the major sabers from the flicks.
As far as I'm concerned there's not much point in speculation over what happened in the negotiations. All I will say is that I was always concerned over the license renewal since the Corgi merger/takeover - after all it means you've got different people round the table for the negotiations, each with new and different agendas, blah blah blah.
I think it's pretty much an inevitability that another company will get the license within a year or so - and we will almost certainly see new versions of all the old MR products - particularly the sabers which were such a staple for MR, and are now completely opened up again. Does this make an MR collection worthless? Far from it - I'm happy with all my MR items. Is it bad for the long-term collector - definitely as the chances of seeing any of the more obscure items (like council sabers) in any near term timeframe are very low.
I hope they get the V2, Mundi, and Mara sabers out this year.
In the words of Douglas Adams - So long, and thanks for all the fish.
