The new poster was revealed just a moment before the first trailer for Star Wars: The Last Jedi was shown to the crowd at Star Wars Celebration Orlando.
As great as the trailer is, the poster is all of that awesomeness in a single image.
We also see Kylo Ren, on the opposite side of the lightsaber beam.
Luke Skywalker takes up a huge portion of the poster, giving us the impression that he will be a major part of the new film, a drastic change to the cameo that was essentially all we got in Star Wars: The Force Awakens.
