To clear it up:
This was a trailer shown at the Star Wars Celebration II in Indiana last weekend. It was specific to that event. So whether this qualifies as a “spoiler” or a “trailer”…um…you decide.
But yeah, Yoda rocks. It’s seeing things like this which makes life worth living.
Of course I knew, Larry. 
And I agree wholeheartedly with you on the whole books issue. My SO has read many of them, and I’ve struggled through a couple, but . . . yeesh. Though, to his credit, Timothy Zahn can actually write.
Well I hope the full fight scene does him justice. Since Yoda never had to fight, you just knew he was the most bad-ass Jedi in the universe. I hope the CGI can live up to my imagination.
From what I’ve read, it’s a spoiler. but you’re not the first to have let out that Yoda kicks ass in Ep II. Last week’s Time Magazine said:
If bleedin’ TIME knows about it, it ain’t no geek secret.
Yoda the action hero was mentioned in passing in an article in todays USA today.
Not much of a secret any longer eh?
