And for that, I think it's a very safe bet that Jarvis *isn't* Ultron.
Because Jarvis is not Ultron and it's important that they make that distinction in the film. We don't really know how the emergence of Ultron is going to play out.
Even if Jarvis is somehow corrupted into being Ultron, they need to show that they are two separate characters and by using another actor's voice, that is the best way.
Anyway, I'm looking forward to see what they come up with.
