I don't watch CW and have never been interested, but I read this in an EW article:

Well, mostly. Filoni acknowledges that the order to resurrect the Sith Lord came from George Lucas himself, who became more interested in his Phantom Menace creation while developing Savage Opress for the last season of The Clone Wars

Why am I not surprised? Just plain hilarious at this point. Obviously Georgie boy wants to increase fan interest in Darth Maul to boost ticket sales for the 3D release of TPM.

The guy is such a hack.
