I think we all need to catch our breath here and relax. ALL OF THIS is rumor and innuendo and until Disney officially addresses the "mature" Fox library they own, I wouldn't personally get all worked up over this.
My feelings are these: Disney can do 1 of 2 things here. 1.) They can decide to keep the VALUABLE adult IPs like Predator and ALIEN and release them under their Touchstone Pictures label or create another "adult oriented R rated/Risky PG-13" movie label to release them under or 2.) Sell off the IPs to another movie studio like Warner Bros(who I'm sure would LOVE the ALIEN and Predator franchises among others).
I think the most likely scenario is that Disney will indeed KEEP the ALIEN and Predator franchises along with the other adult leaning franchises.
I do not think for one moment that Disney stock holders would like hearing that the first thing Disney does after spending 71 billion dollars is to jettison some of the most arguably known IPs in the world in ALIEN and Predator. If I was a shareholder(I wish haha) I'd absolutely be opposed to Disney selling them off or shelving them.
I'm sure Cpl Hicks and some other established members here have some very solid sources (I've been here quite a long time but lurk more than post) and all I would suggest is that there *MAY BE* some FUD being thrown around by upset Comcast shareholders or "sources" who for one reason or another didn't want Disney to close the deal. So just be weary of "rumors" or "insiders" contacting you with this kind of stuff.
I just don't see Disney getting rid of these franchises.
Cheers!
