Over on the CBR forums (and pointed out to us by some helpful members of the iFanbase), it appears that we have our look at the full roster of Secret Avengers:
As everyone suspected, there's (a godawfully costumed) Steve Rogers leading the Secret Avengers. And as no one guessed (not that I can recall, anyway), the final member of the team is Nova.
Yes, that high pitched squeal of delight was from some dude in San Francisco with bitchin' sideburns.
So we have Steve Rogers, Moon Knight, Beast, Valkyrie, War Machine, and Nova. I have to say, I am pretty excited to read this one. That a pretty nice group dynamic. And boy am I glad we went through all that sturm and drang to get Steve Rogers back so he could fight evil dressed like someone out of the bad old early 90s days.
