Is this supposed to be the Avengers movie version of the JL? They got a big strong green guy, an archer, someone who fights in American patriotic garb,.. Hawkman would be the Thor.. Katana and Catwoman would be Black Widow. They even got Waller to be the Nick Fury.
This just leaves Vibe and GL to fill out Iron Man. Its a stretch but I think I've cracked it.
The mistake was probably made because they were getting ready for Comic-Con and the last minute change was because they just finished up at Comic-Con for today no doubt and scrambled to get online to change it.
It's not a comicvine quest though.. its a whiskey media quest, hosted by Giantbomb's Ryan Davis.
Doesn't bother me though.. now I get to get the quest at the same time the show actually starts.
