Well here are some of the newest details on the 991 911 set to be revealed later this year.
Main Details
Do Want-7spd Manual or PDK
-3.4L 350 HP Carrera (Same as Boxster/Cayman with 10+hp), 3.8L 400 HP Carrera S
-Larger yet lighter (Extra length will help with hybrid version which will be a 991.2)
-Revised interior, kind of a mix between a 997 and a panamera, kind of neat I suppose, makes it more like a GT
-Electronic hand brake
edit: Also, Carrera & Carrera S will be first out, I would asusme that other variants will follow in 2012 aswell, perhaps still as a 2012 MY?
