Nothing is confirmed from any of these scraps of information, except that the hype for Avengers: Infinity War has reached a brand new level.
Adding to this melee of information is the suggestion that Thanos is actually the main character of the film.
Marvel ensemble movies are already crowded affairs, and Infinity War is set to be the most crowded lineup to date.
The black background and red logo is presumably only for production purposes, meaning it’s not likely to crop up in any of the forthcoming marketing for Avengers: Infinity War.
