If I had to guess, I'd say they're going to nerf AK slightly, but leave CM and the Primals alone–the former, because it's story mode (they may adjust the reward down), and the latter because Titan is the only real barrier that prevents everyone from getting their Relic right away (which is a good thing). But that's just wild speculation. They could just as easily put HM Titan in CM, make Demon Wall immobile, and triple the speed of the Stalker in WP.
