Microsoft known showing WP7 Oct 11, shipping Nov 8
Many of the launch details surrounding Windows Phone 7 were supported this afternoon through a leak. Citing only "people familiar with the matter," the WSJ said both the October 11 unveiling in New York City and a subsequent November 8 launch were accurate. Despite talk of T-Mobile devices, only AT&T would have WP7 models at first, the sources said.
The initial phone mix would be limited to one device each from HTC, LG and Samsung. The Mondrian is known to be HTC's example, while the LG Optimus 7 and Samsung Cetus would fill out the lineup. Microsoft has already said it will have to pass on Sprint and Verizon until 2011 as it isn't ready for CDMA at this stage.
None of the involved companies have confirmed the dates, although Microsoft is known to be having an open house event in New York City on October 11 and has had publicly accessible details pointing to a November release in the US.
The launch is important enough for Microsoft that it's devoting $500 million in marketing to just the fall launch, which also touches on Canada and Europe. Its launch is the company's greatest gamble in mobile to date, as the developer was willing to engineer a complete reboot in a bid to stay relevant next to Android and the iPhone. Windows Mobile's market share has been in freefall for over a year and in overall decline virtually since the iPhone launched in 2007.
