One problem I have with AW is that's not really that vertical. It ends up being a glorified double jump/ladder eliminator because there's maybe like one or two areas on each map where the boost can actually be used to where you can do something major with it.
Detroit is one of my favorite examples of how AW boxes itself in. You're supposed to be in this urban environment with your jetpack, and what's the only thing you can fly up onto? Cargo containers. And like one higher window. The entire map is completely ground level. The Manhattan map in MW3 is like ten times as vertical as you can go up and into the buildings and down into the subway, fire out into the main street and vice versa, and so on.
The maps in BOIII seemed to be much better about the whole letting you get to anywhere within your powers aspect because there's not an invisible dome in the sky since you could never reach it in the first place.
Still think Titanfall was the movement gamechanger, not AW, but the Titans really overshadowed just how available every inch of those maps are to you. It took me a while to realize how much more effective I could be and how much nobody else was really doing it, when I started leaving my Titan on Auto and assisting it by running all over the damn place helping clean up. Especially when it would take on other Titans. To go back to Detroit, it'd be hott running along and scrambling up those buildings to higher vantage points as you battle with guys hovering around. If that's what you want to do with the ExoSuits. (Actually, I just knocked that idea into my head, the ability to completely ditch the suit and rely on just wall-running/etc. vs. people in the suits but get another slot or two in the pick [X] loadout.)
I guess Infinity Ward will have had just enough development time to scrap whatever Ghosts 2 was and take all this, BO III, AW, Titanfall, Siege, hell even Black Ops II, into account for their game. They wouldn't be the first series originator to get kicked off their franchise and then killed off. They can ask all the Neversoft employees that joined them. Though the three studio cycle thing does seem like a really smart idea. I always thought like Madden/NBA 2K's developers should split into teams operating on multiple cycles so they'd get more than ten months on an aspect of the game. Even if that meant say, franchise mode, went mostly unchanged for a year or two.
Part of that is why the Live thing was so baffling, they deliberately took a year off of the game, and then didn't start development until the regular 10 months out start-date.
