2014 a4 model year releases
 

I just saw a 2014 a4 at local dealer.
I am confused that in reading various articles I thought it was going to have significant changes. Did not appear much different than 2013.
The articles showed pics of a revised body style, much lighter and even more horsepower.
The articles also suggested a release in 2014 rather than late summer 2013
Is this 2014 an interim release with a revised model coming end of this year or next.
Any thoughts are appreciated.
Thanks
