Guys--this is just conjecture, but from that trailer, I think something happened to Baird! He's nowhere to be seen in the whole thing. At first I assumed he was with them in that scene where they were standing on the big box. However, upon closer inspection, you clearly see Marcus, Dom, Cole, and CARMINE.
The plot thickens?
Edit: Again, no one tell me if I'm right, or even hint at it. Only respond if you don't know what happens either.
