It's not difficult to understand why people believe Abrams is getting itchy feet. This is the guy who initially turned down the job, has refused to commit to the scheduled 2015 release, and has bitched about working in the UK (saying it was making him 'crazy').

These things don't exactly fill me full of confidence in him.

Could be a good thing. Lucas had nothing but trouble and discomfort while working on the original film and look how that turned out. He had no complaints on the set of the prequels and look how those turned out.
