Continuing from the thread's title, there's literally nothing to worry about. Do we still get comics, yes. Hell, we get a metric crap-ton of X-books. As for the potential for X-Men comics to get cancelled, it's simply because they don't sell. Merchandise is still coming out, though they may not be as plentiful. Just go to Hot Topic if you want X-Men shirts or Funko Pop! figures, & go to Toys R' Us if you want X-Men figures, plus there's a Wolverine DoFP Hot Toys figure if my memory serves me correct. And the lack of an X-Men cartoon, the current shows are still recovering from Loeb messing with them & they're basically advertisement for the MCU plus Spider-Man (who may join the MCU in due time), so it's not a big loss. Plus there's the X-Men live-action show that Fox is trying to put out, so I'm sure that'll make up for the lack of a new X-Men cartoon. And like I've said in The Complex, multiple Battleworld locations are specific to the X-Men, something you wouldn't do for a franchise on its way out. In short, the mutants will be fine, & we have nothing to fear. As long as we keep buying the comics, the mutants will stick around.
And before anyone brings up the Uncanny Inhumans comic, the Inhumans have had that title for decades. Plus the Inhumans are an incoming MCU franchise, hence the number of comics that are being released.
