I love the 3D Gascans. Nice to be different in the cinema and also to be comfortable at home while watching my 3D TV. Finally picked up the Transformers ones the other day at my nearest vault so will be looking for The Hobbit ones and of course the Trons.
Don't forget: the value of these signatures are determined by all of us and has nothing to do with the turnover or popularity of the movies. I personally think the Tron's are the most desirable ones and when you look at their prices the collector community agrees with me. As for the future of 3d glasses I think Oakley will stick to releasing signature editions and definitely not release some switch 3d's. Let's see what the future of O-3d's brings us.
