As the image tweeted by show runner Bryan Fuller indicate the uniforms will fit nicely in "The Cage" era the series is set (click here to compare with TOS era uniforms). In addition Fuller also explained why the ship and the show is called Discovery:
One of the biggest responsibilities of a Star Trek series is to christen the ship, and this ship is called the Discovery for a few reasons, not the least of which is Stanley Kubrick’s contribution to the Discovery in 2001: A Space Odyssey, NASA’s vessel, the Discovery, and also the sense of discovery and what the word discovery means to Star Trek audiences who have been promised a future by Gene Roddenberry where we come together as a planet and seek brand new worlds and new alien races to explore and understand and collaborate with.He also explained why the series' main character is the first officer:
We needed to look at life on a Starfleet vessel from a different perspective so we introduced a character who is not a captain, but is going to be interacting with the crew in a whole new dynamic which gives us an opportunity to tell a story about life on a Starfleet vessel.Star Trek books, currently averaging around 6 per year (use to be 1 to 2 per month) has been a constant for nearly 30+ years so it doesn't really come as a surprise that a new series of novels are planned to tie into the series. The first will be written by David Mack who has written a number of Trek Books over the years. Long time Voyager book writer (and Discovery writer's room member) Kirsten Beyer will be overseeing the books to make sure they don't step over any TV show toes. She will also be over seeing a comic book series with IDW that will be published in January. The team for the Discovery comic was not announced.
