The reality of the situation as much as it pains me to say it, is George Lucas competence as a filmaker ended a long time ago. And now Spielberg joins him with War of the Worlds and Indy 4.
There is a slight possibility Spielberg has another good film or 2 in him.
I would not trust Lucas with any level of star wars continuity at this point whether it be comic book, video game, novel, cartoon or film.
And those small films of his he has been talking about since 1983 i'm still waiting for those, while he rehashes star wars and indiana jones to were they are just crap series now. Only 50% of the star wars series and Indiana Jones series are good.
When was the last time he brought in new writers and allowed them to do their own thing. The Genddy animated series.
If any more star wars films are made they should be made by Different writers or directors than Lucas or any one currently employed by LFL. The Clone Wars 2008 cartoon could have been good if Filoni was given free reign with the writers and George only took on an executive producers role.
The live action show will suffer the same fate if lucas runs the whole show.
