USB OTG function coming to Windows Phone 8.1

Ex-Microsoft employee, Nawzil claimed on twitter that Windows Phone 8.1 will support USB OTG over mass storage and will manipulate the files on the device using a File Manager. The feature will work via USB On The Go (OTG) and will presumably require a cable like the one pictured below.

It will be of a great help for the users who own devices like Nokia Lumia 925 and 1020 that doesn't have support for external SDCards. A full USB OTG implementation would support cameras, USB Flash Drives, Mice and Keyboards, but I must say that we should not raise our hopes too high.
