True, but it may not though. Especially if an Ultron story concludes in avengers 2. He already exists by the time IM3 starts, and it just so happens that he starts to become more self aware/sentient. He evolves, and becomes the villain in avengers 2. Then, if Ant-man takes place in the past (wasn't it rumored to do so?) It would probably cover a bit of Ultron's origin at some point. I don't think it would be THAT confusing
