Well let's assume that HT is working on this now. Why? I have a feeling they'll want both Cap and Iron Man out in May when the film is out similar to what they did with Thor especially since the Iron Man tooling isn't that far off of what they've established other than coloring and chestplates and Cap will most likely be a costuming issue and HS to match the molded cowl. I think they'll go this route because they in theory might have a full team to be out for the film which means just from that poster a possible 7 figures. 2 for Q2, 2 for Q3 and probably 3 for Q4 with the Hulk coming in the later end of the year.
That means we'll see a Preview and Order in January of next year which means we'll get teases probably in December (if they follow the Thor idea) so we are only about 4 months give or take from seeing some HT Avenger product.
