Industry rumors usually come with a heaping helping of salt, unless they're being issued from a trusted source. In this case, it's Mary Jo Foley of ZDNet spilling some beans regarding Microsoft's release roadmap. Though we've already caught wind that Windows Phone 8 devices would be arriving sometime this fall with nearly all major carrier support, Foley's source is now pegging the RTM build of that mobile OS for September, with the finalized consumer version and accompanying hardware hitting the marketplace in November. Given that timing and an impending October 26th bow for Windows 8 also on the horizon, any plans Redmond might've had for a dual platform launch will have to be shelved. That's all she wrote for now, folks -- we'll surely find out more concrete details in the coming months. So, take this gossamer morsel for what it's worth.
