According to the Marvel Comics Solicitations for November, the Joe Quesada written "NYX" has been cancelled, with November's issue #7 planned to be the final issue.
Just a couple of weeks ago, Joe Quesada addressed the publishing plan for "NYX" during the Cup O' Joe panel at Wizard World Chicago.
"I've plotted through issue seven. There have been scheduling problems, but we will get to issue seven which will resolve some points," said Quesada. The series as a whole will be reviewed at that time as to whether to continue.
The solicitation text for "NYX" #7 reads:
Written by JOE QUESADA
Penciled by ROBERT TERANISHI
Cover by JOSHUA MIDDLETON
"WANNABE" PART 7 (OF 7)
FINAL ISSUE! As the last chapter of Kiden and her friends' saga comes to a close, the kids come to realize why they have been brought together and what it really means to be a mutant in the Big Apple.
