Knowing JJ, TROS will open with Rey and the gang rescuing a comatosed Rose from the palace of a vile gangster colleague of DJ's on Jakku, will then have Rey return to Ah-choo to find out that she's a Skywalker from ghost Yoda, have a long boring chat with force-ghost Luke about "certain points of view" (ie why he never told her - her family link to the dark villain) which will lead her to surrender to Kylo, who will take her before new-Palps aboard the arisen-from-the-ocean DS. Fortunately Poe will lead an uprising of indigenous creatures on the nature planet below (aided by Chewy, 3PO and R2) that will defeat an entire legion of Palps' best troops as Rey and Kylo battle with Palps saying good... good... as the FO fleet prepares to destroy the last vestiges of the Resistance fleet just outside.
And it will all feel young (Palps will look like Chris Pine on a bad day) and Star Treky and have lots of lens flares.
