As others have mentioned, I would not expect any changes to the drive line. I did hear that the '14's will have auto dimming outside mirrors. I'm not sure if they would be standard or optional. I have had the inside mirror like that in both my previous WRX as well as my current Impreza. It is something I have come to like a lot. It would be nice to have the outside mirrors dimming when some bozo decides to tailgate.
