Yup, just saw one in my LBS today. It looks okay in pictures (I hated it when the pics first leaked), but to see it in person is an eye-opener. It's a sweet looking bike! I didn't ask to use a scale, but with 808's and DI2, I'd put it under 18 lbs.
From what I was reading here and on Specialized.com, I though I'd have to go with a small (I'm 5'11"), but after seeing it, I'm definitely gonna go with a medium.
I'm already planning on selling both my road and tri bike to get on one of these.
