Based on what we’ve seen/read so far about the plot it seems very likely that the film will open with Poe landing his X-wing on Jakku.
I think that’s correct, yeah.
(Also didn’t we get a confirmation somewhere recently that Anakin’s lightsaber had been recovered from the lower-levels of Cloud City by some maintenance people or something similar? So why would it be floating through space? Also how the heck could it get half the way across the galaxy from Bespin to Jakku?)
I believe the story is that Snoke (Kylo’s boss) collected it from Cloud City (with the duel still going on overhead) and we may still see this in a Maz-and-the-Force-enabled flashback. Much later, something happened (an explosion or something) that caused the saber to fall out of Kylo Ren’s shuttle…and land on Jakku.
