The Forever arc wasn't acknowledged in any other book because it was mainly a Fantastic Four arc and one could argue it was a self contained temporal event. Just like the Ultron future we saw at the start of Bendis's second "Avengers" run. Or how about Amazing Spider-Man having Doc Ock basically take over the Earth right now, and have the Sinister Six incapacitate the Avengers? It is possible of course that these various events take place during several different time periods of the year. Who knows though.
