1. STID
2. Elysium
3. Pacific Rim
I'll probably check out Ender's Game and Oblivion and After Earth if they get good reviews.
I'll also most certainly be seeing Iron Man 3, Man of Steel, The Wolverine, and Thor: The Dark World; if you consider those sci-fi.
Chances are I will also see Star Wars Episode III: Revenge of the Sith - 3D and maybe Attack of the Clones - 3D if I'm feeling particularly crazy. Because those are definitely sci-fi films. Not science fantasy.
