Star Wars will never not have that problem of every planet essentially being a theme setting that makes the universe easily digestible to the audience. Tattooine is the desert one. Dagobah is the swamp one. Hoth is the snow one, and Endor is the... you get it! Think of it this way. If aliens landed on Earth in the middle of the Sahara, and declared "it's a desert planet. Nothing to see here!" they would be applying about as much scrutiny to our planet as we do to Star Wars.
You can see why JJ Abrams would be tempted to change up the formula for [Star Wars: Episode VII — The Force Awakens](tag:711158), and introduce not only new planets into the Star Wars mythos, but diverse ones too. The most varied and self contained planet in Star Wars movies so far would likely be Naboo, introduced in the prequel trilogy. The appeal still kind of boils down to one side of the planet having Jar Jar Binks on it, and one side... not. What changes do we know JJ Abrams has made so far to Star Wars Episode 7?
The first bait and switch to occur in the run up to Star Wars Episode 7 was the revelation that the desert planet featured in the now iconic trailers was NOT Tattooine. Little has been revealed about the planet Jakku, other than it looking exactly like Tattooine, or more aptly exactly like the Abu Dhabi desert where The Force Awakens was shot. It seems a little odd to introduce such a similar planet to Luke Skywalker's home world just for the sake of duping the audience.
Still, the special charity announcement JJ Abrams made with the adorable merchant puppet does suggest there is some infrastructure to Jakku. Perhaps it borders on a level of civilization that even rivals Tattooine. It's yet to be revealed why characters like Rey the Scavenger and Finn the Storm Trooper are toiling away on this mostly dead planet. Perhaps they themselves are leftovers from a huge battle, fighting for survival on the edge of the galaxy. The trailers for Star Wars Episdode 7 have thus far focused mostly on Jakku, but where else might we see?
Where is Luke Skywalker?
Now there are a lot of a assumptions going on here. Firstly that the above picture does indeed contain Luke Skywalker. Secondly, there's the rather dubious idea that Luke would be in some form of hiding as Obi-Wan was in A New Hope. If the empire has indeed rekindled or even continued it's dominance, this wouldn't be surprising, and come on! He's in a hood in what seems to be some sort of encampment. How am I not supposed to think that?
There's the possibility that, if Luke has reinstated the Jedi order, we could see scenes set on the city planet Coruscant. Those images would however be rather reminiscent of the prequels, and I'm not sure that would be JJ Abrams' intention. Then there's the lake which X-Wings fly over in the trailer. This seems to be a much more Earth-like planet, though I still doubt there's any chance it will turn out to be Naboo. And then there's Kylo Ren...
The shots of Kylo Ren in the trailer are incredibly brief, and it's hard to tell if he's on some kind of fire planet, or if there's simply a fire happening around him. I'd be totally fine with it not being the planet Mustafar, for that setting was basically the product of George Lucas looking at a volcano and thinking "needs more volcano". In all likelihood, Star Wars Episode 7 will be steering clear of referencing the prequels, or any other established Star Wars planet, with its setting. While it will be a shame not to see Tattooine again, a new approach to the planets in Star Wars is good news for fans, for it means discovering something brand new all over again!
