Fan summary from a screening of the first 25 minutes of the film:

The huge thing here (as I see it, anyway) is that there’s mention of the Whills, and maybe the Chirrut Imwe character is one (whoever’s writing this is vague as hell). If they’re explicitly bringing the Whills into this, it could be huge. If this non-Jedi human is one, I’m guessing they’ve made the Whills into an order of Force-believers separate from the Jedi who concern themselves with keeping a historical record of the happenings in the SW universe.

Also, apparently there are no wipes.
