I was about to order a pair of early '13 fenders from Rootlieb yesterday, and decided to email them a photo of the front lip on a early fender just to make sure. Turns out, what they sell is not early at all! I don't know how many of you have original fenders on your cars, but I thought I'd mention this. The fenders I'm talking about have a bill that sticks out like a '12, but is even with the rest of the skirt on the fender. Just guessing, I'd say the angle is about 20-30 degrees.
There's a pretty good picture of them in this picture:
