I liked the teaser. Will we see a longer first full trailer attached to Endgame, or maybe on May 4th? Sand planet is definitely Tatooine. If this is truly bringing the Skywalker legacy full circle, then it would make sense to be back on Tatooine. Plus there are rumors of the Lars homestead being rebuilt for this film. I think there may be a bit of a misdirection with the Tie Interceptor - maybe some type of training session?
The Palaptine laugh at the end may be misdirection as well, and ties into the possible death star remains on Endor? Like another post said, maybe the soul or spirit of Palpatine resides in the remains?
Hopefully Abrams can pull it off, and remove some of the let down from TLJ. I don't "hate" TLJ. More disappointed that what was potential was there at the end of TFA, was completely ignored in the TLJ, along with a weak storyline about ships being low on fuel. LOL
