Eh. You look at the Big 6, mainstream is already homogeneous. It's been that way for awhile. I don't see how going from 6 megacorps to 5 will really change anything. (I'd also like to suggest that said megacorps do not represent "cinema," however we may define it.)
Here's a list of films under 20th Century Fox's banner from 2000 on: https://en.wikipedia.org/wiki/List_o...%80%93present)
Mostly it's multiplex crap like "Taken 3" and "Alvin and the Chipmunks: Chipwrecked." I don't see much that couldn't be produced at other studios. So what exactly are we mourning?
