Microsoft announced earlier in June that current Windows Phone devices would not be able to be upgraded, at least officially, to Windows Phone 8 (although we are sure a few hackers out their might attempt an unofficial upgrade at some point). Instead, all those Windows Phone products out in the world will get what Microsoft is calling Windows Phone 7.8.
So far, the only new feature that Microsoft has revealed for Windows Phone 7.8 is the new Start screen, as shown in the video above. WPCentral.com claims to have heard directly from Microsoft reps that the Start screen will be the only new addition for Windows Phone 7.8.
However, there is now some evidence that Microsoft is in fact holding back and there will be more than just a new Start screen coming for current Windows Phone owners. WPCentral.com points out that Microsoft's Channel 9 video site has a recording of a presentation made for the recent TechEd Europe 2012 conference.
During the presentation, which concerned Windows Phone app development, Senior Product Manager and Windows Phone team member Larry Lieberman answers an audience question about what else might be included in Windows Phone 7.8:
Will Windows Phone 7.8 get new features as well that you can access as a developer? Maybe. We haven't announced it yet. All we've announced is the new Start screen at this point. Sorry, nothing new to announce. You're asking me stuff I can't answer.
The answer definitely sounds like Microsoft has more up its sleeve when it comes to Windows Phone 7.8. Perhaps some more features that are supposed to be exclusive to Windows Phone 8 might find their way to the Windows Phone 7.8 update after all.
