It won't be a few months later. It will be a couple of years later. In terms of the publication dates of the original comics, Defenders is well ahead of Avengers. In fact, this would argue that Defenders vol. 2 should be fast-tracked to maximize the amount of time between the two Masterworks volumes that will include the A/D War storyline.
