Because the Surface 2 is the actual Flagship Product not the Pro 2.
Nope, I stand by that... I was able to spend the weekend before the September 23 launch with the Surface Team and the Surface 2 is designed and held as the purest Windows Experience. They like the Pro and what they have done with it but is still a work machine at the end of the day. They get giddy (Panos and all the way down the ranks) when they talk about the Surface 2.
Surface 2 is what the trajectory of Windows is....
