2011 was the LCI, middle of the lifecycle, so next redesign will be in another 3-4 years. 2011 will run through the normal run I suspect, 2012's will come out next year in the August time frame I suspect.

As for changes, only things scheduled are a few additional smartphone features and possible LED headlight halo's (unconfirmed) but they will be added to production next week - around October 10th, and that should be it for the 2011.
