This is slightly off-topic, but one thing I wanted to mention, was that I recently noticed the prequels were doing Yoda's speech pattern to death, while in Empire Strikes Back, Yoda doesn't take his speech pattern quite as far as he could have.
Like, "Size matters not. The only difference is in your mind".
He could've said "In your mind, the only difference is".
In Episode 3, he'd say EVERYTHING that way.
Seems like a continuity problem to me.
