As long suspected, users of the current Windows Phone 7.5 platform won’t be able to upgrade to the next major version of Microsoft’s smartphone operating system, Windows Phone 8.
Instead, they’ll receive an update called Windows Phone 7.8. The only feature that Microsoft has confirmed will be included in the 7.8 update is the new Start screen with its full-width tiles and greater customization. However, company representatives left open the possibility that other Windows Phone 8 features might be included in the update.
At least they’ll get something in the 7.8 update, unlike some other green robot I know.
