Well this show certainly looks promising!! Like any show, I would imagine it will stand or fall depending on the strength of the guestlist. First-time signers and some big hitters (usual suspects - Viggo, Bean, Ian, Cate, Hugo, OB) would be a fantastic way of ensuring a big turn out - seems like stating the obvious but after over ten years of LOTR collecting I would love to fill some major gaps while starting up a Hobbit-based collection with a strong guestlist.
Obviously this won't come cheaply but for the big names I would certainly be prepared to dig deep!! After seeing the success of the recent Trek convention in the Exel, I really hope the same of guest quality can be obtained for Middle Earth!
