I definitely would like to see Frodo and Sam revisited. Especially if they're making/using a new body.
Now, I like my Sideshow Frodo and Sam. I really do. I still have them displayed. And yes, they were some of the best LOTR figures Sideshow made ... but there's room for improvement and I'd like to see what Asmus can do. The scale is still way off on the SS hobbits and I'd love to see Asmus take the opportunity to fix things this time around.
I just don't think it's a good idea for Asmus to aim for making their hobbits the same size as Sideshow's. This is the opportunity to make things right. It doesn't make a ton of sense to knowingly make the same mistakes SS made.
I understand not wanting to immediately repeat the figures that Sideshow made, but with Aragorn and Legolas already in the pipeline (and at least a stated plan to do Gandalf the Grey) that's already half of the six members of the Fellowship that Sideshow managed to make. With all the other figures they're producing, I'm not really fussed about repeats. And it's fine with me if they want to do Gimli, Merry and Pippin first, but I still would like them to do a properly scaled Frodo and Sam, too.
Just my two cents.
