None of the "Young Avengers" are named either but I'm guessing we will see at least some of them, at least as cameos/background filler.

I'd say definitely not the full list, but at least the ones that are signed and ink dried.

After showing nothing but chairs with people's names they had RDJ walk down and sit in his chair and then he gave people the Shhhhh single and walked off. I doubt this is all the names of everyone who will be in the movie.

They also released this poster below with the caption "It All Leads To Doom".
