It seems alot of people reckon this line is coming to an end. After Gandalf is released there is no more 12" love (
) I think Merry and Pippin will definitely be made... as many peeps have said - they wouldn't have developed the hobbit bodies to only make Sam n Frodo would they?
I reckon all of these 'the LotR 12" line is dead' theories are people just preparing for the worst so they can be pleasantly surprised if/when new announcements are made.... or it's to provoke a reaction from Sideshow to make a comment on the future of the LotR 12" line.
I sincerely hope it does carry on... with the new SS bodies and armoured figures being released the LotR line could really soar to new heights!
Another belief is that SS are pacing themselves until nearer the release of the Hobbit movies and with these new movies replenishing the LotR enthusiasm in the fans.... gather momentum from there?
The only thing that really bother me is that Sideshow have discontinued other licences without any announcement or anything... was it the Buffy line or something like that?
So to answer the OP's question.... if any figure will soon be announced as 'the LAST LotR figure'... it will be Gimli... but who knows really? Anyone got a Palantir handy?
