The proposed origins movie for Magneto should be great, since there're decades of back-story to cover there. Assuming they choose to go into all that, rather than skipping straight to recent history as they did with Wolverine...

It'd be awesome to see how Magneto went from brilliant philanthropist and humanitarian, to virtual 'enemy of the people' and opposed to his old friend Xavier. Also, such a movie also promises lots of Ian McKellen and Patrick Stewart, which makes me happy.

Curious... how could they make a Deadpool movie interesting, given the events of Wolverine? For most of that film, he's just a mutant soldier with remarkable reflexes, swordsmanship and co-ordination. And a 'tude. I'm not sure he'd be interesting or unique enough to carry a film on his own, not unless he's wildly re-written from the version of the character we were introduced to recently.
