If I had to guess (and I do), I'd hazard that the "loadouts" aren't going to have a big variety when it comes to weapons. If they're smart, they'll limit it to choices between the assault rifle, the marksman's rifle, and other fairly balanced, but when combined wisely, gameplay-changing choices. If all goes well, the heavy hitters and power weapons will still be scattered about, like in the previous games, requiring the fast-paced, jack-of-all-trades gameplay we've come to love.
