A few months ago (either just before or just after Civil War started) Bendis said he was going to give Ultron an update, which included upgrading his technology since a big robot with an evil grin isn't that advanced anymore. Since then its also come out that the new Ultron will be a woman instead of a man.

Marvel has posted the cover to Might Avengers #2, which features the new Ultron.

I must say this is interesting. I wonder if Ultron is truly a woman or has he somehow found Jocasta and twisted her?

I think it is Ultron.

Reminds me of Athena springing to life fully grown from Zeus' head.

If you can't mate with the girl of your dreams, the next best thing I guess would be to become her!
