Stark has had his arc and RDJ might not want to be in any more solo movies. A2 shouldn't be exploring Stark's conflict after creating Ultron since we've already seen the character in so many dark spots during his life. Pym is the one that will be getting a solo movie directly after A2, and I see it as the chance to show Pym's struggle with the events in AOU still very fresh on the audiences' minds. I think it's the route they'll take at the moment, but only time will tell.
I'm wondering the same thing tho the part where Logon goes back in time and kills Pym as part of a similar explanation as to absence in the other films.
It would be a great explanation but still where would Ultron come from the whole movie?
