I agree with what others have said, I'm pretty pumped for a Cap movie as well. It sounds like we'll see something about it at Comic Con this weekend, as Chris Evans/Hugo Weaving will be there signing autographs. Plus, I have a feeling there might be some big stuff going on at the Marvel movies panel. As far as the costume, I like it as well. From what I have read, I think he has 2-3 different costumes in the movie for different reasons (I won't get into in case of spoilers), so the wings may show up on one of those. I do think the art we've seen so far represents the "main" Cap suit.
I was sort of wondering what you thought of everything so far (casting, costume, etc.), being such a big Cap fan Scott. Should be a great year for comic movies next year, specifically for you MN guys (Scott/Jeff) with both Cap and Green Lantern next summer. Hopefully they'll both be great, as well as Thor and X-Men: First Class.
