According to ICV2, Star Wars III: Revenge of the Sith will be released on November 1st and will include, in it's bonus features, a short scene showing Yoda land on Dagoba.
At last we can reveal to the public...at last they will know how Yoda got there.
I don't know about all of you, but I thought Lucas spent too much time during the "prequel" series explaining to us how things in the original series were grounded and not enough telling us an epic story. It could just be me. Lucas could have the higher ground and we all know that if you have the higher ground you can't lose.
