So... what do we know so far?

• Nothing is set in stone!

• The series will take place in the 20(?) year period between the end of Episode III and the beginning of Episode IV. During the time in which the Death Star is being constructed and the Emperor is becoming all powerful, hunting down all remaining Jedi.

• All of the episodes will be written at once before production, which probably be atleast a year away. source.

• I'm taking this with a pinch of salt, but according to one site one hundred episodes will be written and shot in australia (which would go along with rumours that Lucas has his eye on Australian actor Matthew Newton). source.
