User blog comment:Jacknapier10/Which characters cannot appear in the Marvel Cinematic Universe?/@comment-24812000-20140424171301

Just like in the chart, I would say the ones in 20th Century Fox and Sony Pictures could not appear in Earth-199999. I'm not sure about Cable, but the others in those categories (also not counting Scarlet Witch and Quicksilver) are still having movies made about them. So for those guys, not any time soon. Maybe Silver Surfer could appear, because I don't believe he'll be in the new Fantastic Four franchise.
