@_Y06_ There will be Windows 10 upgrades for all Lumia Windows Phone 8 devices 🙂 And we will release new Windows 10 models in the future!

While we have long believed that all Windows Phone 8 handsets will be upgraded to Windows 10, it is good to see it in writing, with Microsoft’s official twitter account @Lumia (previously @windowsphone) writing:

Of course its not official until it happens, and we must remember previous supposedly official tweets saying Windows Phone 7 handsets will be upgraded to Windows Phone 8, but so far we are pretty confident this prediction will come true.
