Microsoft's Pink project for its own, self-branded smartphones has gained credibility through a series of leaks in recent hours. Veteran observer Mary Jo Foley maintains the project is real and will provide a software overlay for Windows Mobile 7 with a strong focus on services, most likely involving the Zune Video Marketplace as well as a possible Zune Pass music subscription. One or more stand a chance of being previewed at CES in January, but the OS itself isn't due until the second half of 2010.
