Looks like the odds of Daigo ending up dead have gone up a decent amount (I wonder if that blood will get censored again).

I didn't expect to see Devimon (although he is just a very common sign of evil in general) and if it were to turn out that part of tri's plot was Devimon's doing all along (90% sure that's not the case though) it would be an interesting play on a returning villain who isn't Vamdemon (not counting MetalSeadramon and Mugendramon since they has basically zero of their original personalities).

And that Tailmon evolution... surprising to some maybe? As surprising as a choice between only 2 realistic options can actually get (although you could argue that the last part somewhat evened out the odds).

The sky looks abnormal throughout the trailer and I'm imagining that this would have something to do with Ordinemon's effect on the world or something. But the thing about that ios that we have both night and day scenes with that effect in the sky and I sure as hell hope that they won't pull the old "yeah it's a super strong evil being but it will just sit around in the sky for a few hours waiting until you're ready" routine. At least for the first part of the movie could do with some uninterrupted high tension payoffs following the very rapid escalation in the last few minutes of part 5.

They are still not showing Taichi but after the poster reveal he is basically guaranteed to show up so I wonder if they are just teasing or maybe there could be more to it. I mean it's unlikely but it's possible that Taichi is legitimately dead for the time being and eventually gets resurrected or something.
