Yeah, I think it rises this year, but not to 70. I vote 66,600. :D Since so many religious folks in my area (Christian Reformed) seem to feel that Satan is involved in D&D. May as well make it symbolic!
Gen Con 50 attendance will be 67,667. (Is this the 50th Gen Con or the 50th Anniversary of Gen Con - 51th Gen Con ? )
Gen Con 50 is the 50th Gen Con not including "Gen Con 0" at Gary Gygax's home in 1967.
I think some increase but not at the rate of last 5 years. 65798
