There’s a shot of some red laser exploding into a rock (after the “evil Threepio” shot) that could be “Starkiller II”. That would be a shame.
Besides that though I personally enjoyed the trailer. But I’m near certain Evil Rey is a force vision. The marketing is pushing the final battle to be Kylo and Rey (with a blue saber) on the Falcon in the rain. They show a shot of it in the trailer, and Rey very clearly is on the light side.
I think that from these clips Starkiller II and Evil Rey Vision are both certain.
