I think what they mean by that is that while there'll still be the in-the-'Mech-headcapping-grunts-with-your-Gauss-Rifle action, more emphasis will be put on your leadership skills... MW4 has the potential for some of that if you are willing to have your fingers fly across the keyboard to boss your lances around (also makes most of the later missions easier and improves their survival rate), but this will also include more electronic/information warfare, so we may get ghost images, the need for Active Probes to improve sensor data, not necessarily knowing what the enemy is equipped with until you detect them using it...

I can see great potential for when we hit 3050, or when you're doing black ops against skunk works facilities...
