Kill Osama Bin Laden (or whatever the title is now)
Terrence Malick's new movie
The Silver Linings Playbook
Voyage of Time
The Master (official release date is 2013, but many people are predicting it to get pushed to late 2012 considering it's been in post-production for months already)
That's my list at the moment, although I expect it to grow as I discover more films coming out. I was looking forward to WWZ until I found out they're just slapping the title onto a generic zombie apocalypse movie and scrapping the multiple stories from the book.
