Those are so freaking cool. I can't even say which one/s I'd want if I only had the opportunity to get one, or a few.
I won't have time to attend all the panels to potentially put together a full set, heck I won't even be there Sunday or Monday, but if I see a panel that catches my attention, I may try to hit it. If I pick up any medallions I'll let everyone know and if someone needs it/them to complete a set, we can talk about some sort of trade or something.
