So, in the Disney+ commercial, Wanda answers the phone with "Vision residence". This implies that "Vision" is functioning as a family name, suggesting the title "WandaVision" is not referring to Wanda + Vision but to herself, Mrs. Wanda Vision.
And of course this is with a dual or triple meaning of "Wanda on television" and "Wanda is having a hallucination/dream".
All of which is to say that -- quite apart from the likelihood that he isn't actually there in the first place -- I expect the show to be more about Wanda than Vision.
I mean, completely. They're starting from a 100% different starting point and premise. Other than the high concept of a domestic sitcom type life for Wanda and the Vision, there's not really any relation.
