I expect Ultron to be the first supervillan in the MCU to escape and live to fight another day. Even Loki never managed that, he was always captured and defeated. Only in Thor 2 when he was pretending to be a good boy and faked his death did he actually get away.
So being the first bad boy to determine the manner of his exit strategy is pretty bloody strong when you are going up against a whole team of super heroes.
You could argue Winter Soldier was the first, but he was defeated philosophically so that he turned from being a bad boy into good... or at least no longer a threat, ever. And we are pretty sure he becomes Captain America Mk 2 some time in the next few movies right?
At least I hope Ultron gets away. I really hope Hollywood doesn't go all Hollywood and has the bad robot get properly defeated in this movie. The MCU needs villains other than Loki to live to fight another day.
