Windows Phone Thoughts: HTC Gets WP7 Orders from AT&T, Orange

"Taipei, Aug. 10, 2010 (CENS)--High Tech Computer Corp. (HTC), a world-caliber supplier of smartphones, has reportedly received orders from AT&T and Orange for its newly debuted Windows Phone 7 phone, which will be launched in the U.S. and some European countries in the fourth quarter of this year, in an effort to cash in on year-end sales booms, according to industry sources. In fact, Microsoft`s chief operating officer Kevin Turner has confirmed that the world`s first WP7 phone will be available in the U.S. and Europe in October or November, implying that among WP7-powered hardware developers as HTC, Asus, Samsung, LG and Dell, who have been engaged in development of such phones, some have been set to ship out their models."

I'm a bit concerned that we've heard too much about AT&T carrying WP7 and not enough about T-Mobile, Verizon, or Sprint carrying it. Could this mean they don't actually have plans to carry WP7 at launch, or do they simply have an easier time keeping their leaks in check? Is WP7 doomed if only 1 major carrier per country carries it?
