According to the zdnet article linked by recoilednsake:
Update: A spokesperson is now saying the reason for this Metro de-emphasis is not related to any litigation. (I asked if it is related to any kind of copyright dispute that hasn't yet gone to litigation and was told there would be no further comment.)
The spokesperson added:
“We have used Metro style as a code name during the product development cycle across many of our product lines. As we get closer to launch and transition from industry dialog to a broad consumer dialog we will use our commercial names.”
Their earlier literature makes this harder to believe:
> Metro is our design language. We call it Metro because it's modern and clean. It's fast and in motion. It's about content and typography. And it's entirely authentic.
At some point, trying to spin something obviously related to legal issues makes you look silly. Why not just say they respect the established brand and gain nice-guy points?
