I think what swmcbf means is that Bendis first says:
"Age of Ultron is not part of the Marvel NOW! launches, but it is a very large project, and it is coming soon."
"It's ready to go. It'll be in Marvel NOW!, now."
So is it in NOW or not? That's where the contradiction seems to be.
Possibly, Bendis means that Age of Ultron won't be part of the #1 launches but will be released soon after, so maybe it's not a contradiction (at least not in his mind).
I'm not sure exactly what NOW is, but I'm guessing there is a storyline involved and not everything that overlaps with NOW necessarily has direct ties to whatever that story is.
