The Inhumans series? that read like push to me.
There is one inhumans series (inhumanity), Ms Marvel, and MAYBE New warriors if you want to count that one- but that one has just been canceled.
Comparing that to the metric ton of new X-books that launched in the same time frame is laughable.
edit: on top of that, the broader marvel universe has been MUCH more heavily integrated into X-men continuity.
She-hulk is acting as the lawyer handling the last will and testament of charles Xavier.
Magik is now training with (a past version of) Dr. Strange, and will end up as sorceress supreme in 2099.
SHIELD has been canonically established to be who was manufacturing sentinels all this time, and that particular bit of business is causing conflict.
One of the members of team goldballs just ran into the rawhide kid in the 1800s.
Exodus is now working for shield on contract as a telepath.
The Original 5 X-men have crossed over into the Ultimate Universe, and teamed up with Miles.
Cannonball and Smasher now have a child. Sunspot bought out AIM and built his own team of avengers.
Spider Man is now instructing a team of X-students, acting on wolverine's last wishes.
I could go on, but the integration is a real thing. inhumanity has been a bust.
