I haven't seen any either and it's the one that I want. I was encouraged by the comments the Verge reviewer said, which was that the magnets were strong and that he loved it. He had the black however, but still.
My biggest fear is that all the leather loops will be back ordered from the get go. That would be extremely disappointing. I would then try to get a stainless steal with a white sport band and buy the leather loop separately when it does become available.
I hate to admit how much I'll be disappointed if I can't get any watch on the day it launches. Guess it's become such a habit with the iPhones and iPads that I'd hate to break it. I haven't missed one yet (knock on wood). Anyone else feel this strongly?
