The only true trustworthy spoiler source for TROS is RedLetterMedia. According to them, we will get time travel and it will get Endgame treatment!
No. I promise you that is not the movie.
What appears to be going around is two spoiler reports.
One is from that Jason guy at Making StarWars. The second is from a guy at Reddit going by name JediPaxis.
Quite a bit of what J/MSW posted seems to match up to an old 4Chan link from quite some time ago.
Then this JediPaxis posted his spoiler report. A lot of it matches up to the J/MSW report, but there are differences. Some of those differences are big.
