I found it interesting that amidst all the usual stuff getting mentioned in the list originally posted, Sandman was planted for a 2016 release.
As far as I'm aware, Neil Gaiman is still only in talks with Joseph Gordon-Levitt about the story outline for this.
It's quite a thing to already have the date pencilled-in regarding a release for it.

Yeah, I'd been trying to remember the last thing I'd heard on that, JGL being it... The last instance I can think of where somebody got a release date whilst in prep was Iron Man 2

Every single reason why I think we shoud adopt the "wait and see, wait and see" approach to the list in the OP.
It's a bit lengthy, but worth a read.
Essentially, they are all projects that have either been previously confirmed or are currently confirmed as being in the early stages of pre-production - except one title.
And the timing of the Superman and Wonder Woman films seems well off to me.
Anyway, have a read and see what you think.
