From what's already been released, I'd probably say Titanfall, as hype amassing around it was pretty massive for a while. It's also been generally highly viewed by a lot of critics. It wouldn't be my choice, but I could see the critics thinking of it. From what's on the horizon I think The Order stands a chance.
I don't think there's really a clear front-runner in the vein of The Last of Us from last year...
