Okay, so we all know that Superman is going to come back in the Justice League movie. The world and his wife knows it. The only way you wouldn't know is if you were the most casual of normies. That or a nomadic eskimo.
So, the big reveal is obviously going to be Green Lantern. And it's obviously going to be Hal. It'd be a nice surprise if it was Jon or Kyle but they're just not as well-known or marketable.

So, what I'm wondering is - when is he going to show?
I think it'd be pretty awesome to have him show up during the final battle with Darkseid but more likely than not he'll just end up being in a post-credits teaser for the GLC movie
