As long as Abrams isn't ANYWHERE near Orci, Kurtzman, Lindelof or Burke, him directing Star Wars might not be such a catastrophe.
But his preferred visual style would still suck incredibly in a Star Wars film. Shaky cam, whip pans and lens flares? Hell no.
The fan thing will be funny. Star Trek purposely didn't give fuck about the fans because it was run into the ground, and they were all like "We're making this for the general audience, and if yo Trek fans HAPPEN to like it, good for you.". But this isn't gonna fly with the Star Wars audience, nor is there any need to do it, so they will be all like "This one is for the fans!" Hilarious.
