It's a comedic parody. It is 2:32 long and nothing looks familiar to any scenes in the previews. This guy has amazing CGI skills. The video was published on 12/2/2016. So I don't know how he could have access to any of the movie scenes. Unless the movie was released earlier in some cities? It does not tell the Rogue One story. It has three short funny unrelated scenes. But if you want to wait, I understand. :)
