Brian Michael Bendis took to his Tumblr today to answer some questions about Uncanny X-Men #600. Because of Secret Wars, the issue will not be released until October.
“It was bumped until after Secret Wars for editorial and commercial reasons. Not my call. This was Marvel. But they have their reasons. It will not effect the story or the impact of the story. In fact it may have more impact on how things shake out after my run.”
The issue will mark the last of Bendis’ run on X-Men titles, which began in 2012 with All-New X-Men #1.
The best take away from this is that Uncanny X-Men #600 will be here, but we just have to be patient.
