I think whatever they end up being, even if they use the name "Jedi" will definately be very different to the prequel era Jedi - or even the type of Jedi Luke was in the Original Trilogy.

It is more that Dark Side users are usually portrayed that way, but not always. Darth Maul started off that way but in his final scene in Rebels Season 3 he is mellow and has an almost brotherly moment with Obi-Wan, whom he had hated for most of his life.

I think this will be about him learning from the mistakes of the past - by finding writings from the original Jedi - or before the Jedi and forming a new order. Perhaps something more like the Bendu.

I am thinking more of him introducing something new. If you look at the Mortis Trilogy in Clone Wars, the bendu in Rebels and the line about Rey sensing "the balance" - plus her sounding shocked as if learning something new that she never expected - and Luke saying "It is no such bigger," I think Star Wars is heading…

"Only a Sith deals in absolutes." Which is itself an absolute. Did Obi-Wan accidentally out himself as a Sith? It is not even his only absolute leading up to that point. *wink wink*

While that line turned out to be correct I wonder if he got his prophetic visions mixed and the prophecy was referring to Harron Ford's opinion on playing Han Solo. :P
