It's too optimistic to even assume they are ever returning in anything more than a cameo in the comics even though their last publication won an Eisner Award. I don't think there's ever been a comic book character that has gotten this much hate. Not even Captain Marvel. The difference is that a lot of people hated the inhumans without ever having opened an inhumans book. They just adopted the "they were going to replace the X-Men and I hate them" line and pushed it to this day. The writing wasn't bad. It only got bad when they got into an event because of the premise of the event. Everyone complains about events because they are cash grabs and poorly written. They were world building for the inhumans and were developing new characters until they did the X-Men event to shut it all down.
