Interesting to see such strong opinions drawn from a trailer that gives us nothing. Anyone can make a pretty cutscene in the industry, it's not hard to make it look good outside of the actual game. I want to see gameplay, I care nothing for this until I see that.
That said, I agree that it seems a bit like the next step that the Black Ops series would have taken. Granted, I liked the campaign in Black Ops II in part, because you got to play with fun gadgets and weapons, so that might not be a bad thing. However, we need to see something that will add a layer of freshness to the multiplayer, because we all know that the multiplayer sells the franchise.
