Okay the latest Ant-Man series with Eric O'Grady (The Iredeemable Ant-Man) was awesome and could easily spin out of the shield continuity established in Iron Man and the new Hulk film, but apparently thats not what they are doing. They are using former Avengers members Hank Pym and Scott Lang as the two primary Ant-Men in the film, and that its likely to be more of a look at a modern successor to a classic old-school hero.
Really I think the amoral Eric O'Grady version is much more marketable, especially since there are far more comedy elements to play up and there are far better costumed personas to explore the past/modern theme they are looking at, such as Captain Marvel. The idea of a teaser trailer featuring O'Grady's encounter with Carol Danvers, I just can't believed they'd pass that up.
