Given that Vision is set to be played by Paul Bettany in Avengers: Age of Ultron, it seems likely that he could be set to appear in future Iron Man movies too. Bettany, of course, has voiced JARVIS since the Marvel Cinematic Universe's inception - first doing so in 2008's Iron Man, before reprising the role in Iron Man 2, the Avengers and Iron Man 3 - and therefore the fact that he is playing Vision could mean that this version of the character is an upgraded version of JARVIS himself. If that is indeed the case, then he will obviously be a Tony Stark creation and an embodied version of Stark's personal A.I. He will, therefore, be wandering around Stark mansion at his leisure, acting as Stark's butler, buddy and security. That would be pretty cool.
