I'm thinking the same thing as far as the origins of both Ultron and Vision are concerned. Ultron will most likely be destroyed in the film with a teaser showing a back-up system of some sort, since that's part of his character - always coming back after being seemingly destroyed.

Vision is a lot more fuzzy. It's possible the version that appears in AoU may be destroyed, but Tony may salvage the remains and rebuild him later (possibly to join the Avengers as a replacement for Iron Man when the group goes up against Thanos in the third Avengers film).
