That is, can you posses the two CPU controlled squad mates in 2-player coöp / split-screen as you can in single-player?
I'd presume so and indeed hope they allow for this. This "Leap" system seems a very natural and essential thing for team- based shooters. I don't know why no one has thought of it earlier. It makes the bot players so much more important and useful and doesn't hinge a coöp centric game experience so heavily on having a full compliment of [human] players.
