We have been watching the launch of WP8 because we are enthusiasts. I think MS has had hopes launching Windows 8 and WP8 at the same time. I think that is the overarching goal all along. While it seems like it's being delayed or whatever, in the Redmond vacuum, I think that was their goal. Suddenly distribute all things Windows out into the world at the same time.
I could be way off, but I don't think it's inability to get their OS out, or lack of readiness by the oems or the carriers. I think this is what MS has been choreographing.
