WARNING: THIS COMMENT CONTAINS SPOILERS!
I think the director may have lied when he said that the relationship between Nick and Juddy is not romantic.
I work in the studio in Brazil that makes the dubbing of Disney movies. Sorry for my terrible English. Here, Rodrigo Lombardi will make the voice of Nick and Monica Iozzi will make the voice of Juddy. Both famous here. The other characters have voices made by normal people. I had the privilege of seeing several scenes of the film, but not all.
To prevent that we gave spoilers of the movie, they cut the film in several scenes and voice acting is done using random scenes (not in sequence), so that we do not know the history of film.
Going back to what I was saying, I think the director lied. I think he did it to not create many expectations about the movie and create surprise for everyone. There's a scene where Nick gives a little kiss on the head of Judy. In another, the opposite happens. Juddy gives a kiss to Nick. But kiss? Yes, the film will have! After solving a case. But I do not know if the kiss was because were very happy after solving the case or because they liked each other. Not a kiss that gives a friend, on the cheek, but a very deep kiss. Very cute this scene.
Emphasized what I say, the director MAY have lied about the relationship between Judy and Nick. Particularly,I do not think that two friends act the way that I saw in the scenes and do not believe that after 48 hours of adventures, will still be just friends.
Unfortunately, the scenes after this episode that would show what would happen to Juddy and Nick after this adventure I have not seen. So I can not confirm the story that many say that Nick will turn a police officer and Judy partner. It seems that this movie will be very long. Can reach 120 minutes.
Here in Brazil the film will debut February 18th, but there will be a preview on February 8th. I`m very anxious to watch the entire movie.
