i said pretty much the same thing. but i thought that it should be mentioned that Pym hasn't actually been Ant-Man for a long long time. he was only Ant-Man as an Avenger for a few months before making the switch to Giant-Man. if he were to appear in an Avengers movie, i'm betting that it would be as Giant-Man.
Scott Lang, on the other hand, has been Ant-Man (in the books) since a little before the 80s. it wasn't even a case of Pym passing the mantle along as part of a legacy. he simply lef the identity behind. he had been Giant-Man, Goliath, and then Yellowjacket before Scott came into the picture. Hank continued on as Yellowjacket.
i think that, in some ways, Hank being Ant-Man is significantly more important to fans of Pym than Pym himself. i guess what i'm saying is that, at this point, Ant-Man is Lang's legacy. his daughter already emulated him. he's currently leading a team as Ant-Man. he hasn't used any other supehero id. i think he's put in too much time to be considered a placeholder.
