I wander if this sort of reveal will have any input in ady's version of PT...

Reveal? There was nothing revealed. Fans have known all of that stuff for as long as I can remember, and those things are part of what made the PT so very disappointing to us. It seemed like a really cool story, and we waiting so many years to see it, then it was nothing like we expected. Not being like we expected would have been totally fine, maybe even a really good thing, but it was done really poorly, and established continuity from the first films was ignored and forgotten.

The only part of it that was new to me was Lucas saying that Yoda doesn't fight. Between being a wise sage and making statements like "War does not make one great", I think most of us just assumed that he doesn't fight and that he'd just use the force to protect himself if it came down to it. It is nice to hear young George agree on this, though.

Mostly off topic, but an interesting somewhat related mention: There was an old animated chess game called Star Wars Chess, Yoda played the role of the white Rooks. Anytime one of the white Rooks/Yodas captured a piece, he'd use the force against them. For example, white bishop taking black pawn would be a Stormtrooper pointing his gun at Yoda, and Yoda waving his hand and saying, "Backwards is your gun" which caused the Stormtrooper to flip his gun around shoot himself instead of Yoda. To take out the black rooks, which were AT-ST's, Yoda would levitate it into the air and use the force to squeeze it into a ball, if I remember right. Hardly canonical, being a silly chess game for Star Wars fans, but I played it when I was fairly young and I think it went a ways into shaping my perception of how Yoda might go about a fight. I mean, when you have the ability to lift space ships out of swamps with just your mind, why use a stupid laser sword?
