One can only hope right? From what I know of game trailers... they never ever paint an accurate picture. I'll have to actually play it to see. But if it takes fps's to the next level (which I'm hoping it will), we could see a new revolution in shooters. Honestly stuff like melee moves, cover OPTIONS (not requirements or basing the entire game around that aspect), and acrobatic moves are the next generation of shooters.
At this point in gaming one genre simply isn't enough. In the classic days one genre was more than enough for the development costs and the small teams that made the games. In the modern gaming era of high budget games and very large design teams, there's absolutely no reason why a game should be just an fps, or a fighting game. These genre's need to start merging more, and hybrid genre's need to be the new norm.
Think about it, a game like Street Fighter should have an action/platformer/beat'em up mode. Why not? You have the characters and their moves, now just make extra baddies and bosses, a world to explore and challenges to overcome all while fighting. It makes sense and while it would take more effort, it would create a much more worthwhile game.
