Personally, what I could see happening is Marvel persuading Wright to drop the "Pym was Ant-Man in the 60's" angle and moving his story up to the present day. Allowing them to still use him in any Avengers sequels while Wright does his adaption of "To Steal Ant-Man" in the solo film with Lang.
that would be the best outcome if Wright intends to keep Lang in the movie. let him tell the story he wants to tell. but also introduce Pym (a viable version age-wise) in case Marvel wants to use him elsewhere.
