Maybe GL wont give a Home world for Yoda, maybe it will or has perished already or been over populated by short wise people. Unknown, purchance another writter will see the burning need to write about it. Maybe like Dark Crystal there are the Supremely wise people and a bunch of violent Trogs and that why Yaddle and Yoda moved home and dont like to discuss it...
Ok, I hope you're kidding because everyone here knows Supershadow is the place to go for the opposite of all things knowledge.
Yoda is not a Whill and as far as I know his homeworld yet remains a mystery. I rather like not knowing, it's one more thing GL hasn't 'explained' (i.e. taken away any chance at debate and speculation). Leaves things open to the imagination.
