Well may i add, there is Fan Expo 2010. It would be considered big aswell since Fan Expo was huge last year. Me and my friend are.
FanExpo is basically 5 expos in 1, theres: Gaming, Horror, Anime, Comic Book and Sci-fi.
It was pretty big when Steve downes was there, also some Charaters from Star Trek that i can not remember to name. Everything else, Everyone is awesome and friendly depending who you come into contact with, thats were we met Moz in his Mark V i believe.
Fan expo is located in Ontario, Toronto @ MTCC (Metro Toronto Convention Centre)
I do not know if you are interested, but im just posting a suggestion.
