Well you got to remember George Lucas sold The Star Wars franchise to Disney so you never know the might put the yodas race in the game.
And you gotta realize you necro'd a thread from almost a year ago, that was before the Disney deal went through.
But you do have a point. With the sale, Disney could finally reveal more about Yoda's race. Which personally, I'm on the fence about it. With as long as it's been a mystery, it would have to be pretty damn epic. If it was just something like "They come from the planet Yod-coolas, and are very xenophobic, and super-rarely leave their homeworld" then it's just going to be a giant let-down.
