Tech site PocketNow, which obtained a copy, says the video hosted by a corporate vice president of Windows Phone program management was intended for Microsoft's partners at phone maker Nokia, The Seattle Times reported Friday.
Among the features highlighted in the video are support for multicore processors, new screen resolutions, removable microSD card storage and NFC radios for contactless purchase payments, PocketNow said.
Also included is the ability for desktops, laptops, tablets and phones to share content, it said.
The video suggests Windows Phone 8 will share components with the Windows 8 desktop operating system including the kernel, multicore processor support and video and graphics technologies to offer "very similar user experience" across a phone running Windows Phone 8 and a PC running Windows 8, tech site Supersite for Windows reported.
