I think the secondary market prices will be somewhat soft as well.
As for the souvenirs - Overkill & Hotwire ($250 max), Laser Viper or Joe cold weather 3 pack ($250 max), Dee Jay with Armadillo ($300 max). All convention items have been on a downward trend on ebay. Even the 2011-13 items have fluctuated (not the '11 set, of course). I think the fan base has reached the threshold for which they will pay. Everything seems to have stabilized, not increased in value over the last two years. People are only willing to pay $300 for a bagged NF Crazy Legs for so long.
