As reported by TrekMovie.com, a set of four new posters for the new movie have been distributed at Creation's VegasCon. The new ones follow the style of the previously released posters and together form a Starfleet delta. I've taken the liberty of tidying up TrekMovie's photos of the posters, matching their colours with those of the first four posters from the movie's website, and arranging them in the delta:
The posters give us first looks at the new Sulu, Scotty, McCoy and Chekov.
UPDATE: The offical website is now hosting nice clean digital copies of all of these.
