JJ is not keeping Lucas out of the loop.
And he did not have Gene Roddenberry to consult on the 2009 movie as he has pointed out.
Problem is how much time can he devote to star wars, with a third Trek feature and a fifth mission impossible i don't think he is going to be the New Lucas , he is going to be a director for one picture and that is it.
It is obvious however that episode VII is the most important because its a vehicle of revival for the franchise only if it makes a mountain of money.
They are betting big on JJ. That or the marketing of toys and whatever else.
