Yup, it's another Harry Knowles b.s. made up story to get website hits.
A Yoda standalone is the worst idea ever.
If it were somehow true, I'd pretty much give up any hope on the new direction of the franchise.
The great thing about Yoda, like other OT characters such as Vader, was the mystery of who he was.
Then the prequels showed us, and it was boring and uninteresting.
Meh.
