Spiderman will be before Mark VII, although USO Captain America will probably be before both
That would make no sense though
May 23rd = Spider-Man teaser
June 6th = Joker teaser
June 15th = Iron Man Teaser
If iron man comes first that means they are working backwards, servicing those waiting the longest last and those waiting the least first
Just going by the typical 2 weeks between each teaser for the Avengers figures with the exception of Black Widow.
It would make sense to see the full reveal of Spidey on its opening weekend
Joker came out of no where so I don't feel that it really counts
Plus my guesstimation was made before the SS Comic-con site said that USO Cap was going up for PO next Friday
