They're showing the first ten minutes of the film in a press/fan event in Mexico right now

Based on what I've read here, I'm not surprised and expected the first scene to play out much (if not exactly) like that.

 

Alright, peeps - if you want my two cents on this situation, I think that *both* accounts of what the opening sequence is are untrue. The only things I think would actually hold water is that they wouldn't show the Luke/Rey conversation and there wouldn't be an opening crawl as part of this sequence, but I'll get into why later.

Firstly, if they were going to show the first ten minutes of the movie to hype people up, then why would they stick entirely with a conversation (even one with a great significance to the plot)? That would defeat the purpose of skipping the opening crawl altogether. Not everyone that will be there is a superfan - some people are shallow and just want to see explosions in space, and if they don't see that there, then they might not be interested in catching the film on the big screen. Plus, they're making a big deal about what Luke's first words in decades are - I don't think that they'd casually give it away a month ahead of the movie's release.

Secondly (and lastly, I suppose), there are too many inconsistencies with the described D'Qar attack given what we know about it. There's ample evidence to show that there are two major space battles in the movie between the two trailers - one above D'Qar, and one in the middle of nowhere. Kylo Ren is almost certainly not involved with the former, even if he is involved in the latter. Poe is explicitly shown flying his X-wing above D'Qar, so we know that he won't be in trouble here. And, perhaps most importantly, everything we've heard suggests that the Resistance Bombers are reinforcements that come in the nick of time, not something that the Resistance fleet has when the First Order initially attacks.

I personally am of the belief that The Last Jedi will open up with another space sequence, because that's something of a tradition for the franchise and it lends itself to beginning things off with an action-packed sequence right out the gate, or exposition followed by an action scene. And that's all I'll say.
