Actually, there's a part of me that would like to see Peggy older, but still in possession of all her faculties, and she provides a sort of touchstone to Cap's past, and a giver of advice as he navigates the modern era and SHIELD, for the next couple of movies, but possibly dying in Captain America 3. It keeps Haley around as a supporting player for the series.
But I can't deny the poignancy of Crimson King's scenario. Gahhhhhh... all
