I noticed it looks like they’re keeping the lightsaber’s pointed tip like in the prequels and also in The Last Jedi. Unless that detail is just for the poster, I’d wonder why they’d keep that continuity when Force Awakens had the classic rounded tip.
Explains why some stuff looks dodgy, like the fake way C-3PO is holding the bowcaster. It was a boring poster anyway, reminds me of TLJ. I really didn't like any of the marketing or posters for Last Jedi. The whole red/white high contrast theme became old fast.
