I don't remember seeing the Artfire at all.
Last year was my first year.
I thought it was pretty solid, though I was disappointed in the lack of Adventures figures. I was really hoping to get my hands on a Roadblock (That Scoop Repaint).
Hopefully next year there is a bit more of a presence of TFCC/BotCon figures in the dealer room. I did score a TFCC Dion (though not with the missiles he was suppose to come with)
Ultimately I did make off with a great haul but what i needed to do was get a bigger suitcase to travel with.
