Haven't heard about it, but it sounds like BAAAD news.
How about episodes 7, 8 & 9??
I still haven't forgiven him for switching from the original plan where Episodes 1,2 & 3 are supposed to play a few centuries prior to the original trilogy to show the Jedi in their prime.
7,8 & 9 were supposed to show what happened again some time after Luke & Leia.
Kinda like the Dune series showing how thinks developed over the ages.
In short the original plan called for 3 trilogies.
Still wondering how he will tie Episode 3 to Episode 4, too many loose ends and to short a timeframe to explain everything, but than that might be the reason why he wants to redo the original 3 movies.
