I think Whedon felt the need to dial Ultron back for Avengers 2 to avoid any Deus Ex Machina cheats to allow the Avengers to miraculously defeat it.
Writers can make Ultron all but omnipotent if they so choose, but the challenge comes in making Ultron a complex character that has exploitable flaws that will lead to its defeat by the protagonists.
Unfortunately, we will likely be seeing the Inverse Rule of Power in effect, which simply means the more drone/clone/minions Ultron spawns, the weaker and more disposable they will be (see Iron Man 3 and his 30+ disposable armor suits). Looks great on screen though.
