Microsoft’s new Window Phone 8 OS won’t get installed on any of the current Windows Phone devices because they are based on a different core- Windows CE (Windows Phone 7) versus Windows NT (Windows Phone 8). Windows Phone 8 will support significant improvements including multiple CPU cores and better graphics.
Microsoft’s senior marketing manager for Windows Phone Greg Sullivan stated that, while it can be done, porting WP8 on older devices would be very expensive. He also stated that the WP8 requires functions like multi-core support, higher resolution screens, NFC and microSD card support. The legacy device hardware can’t make use of Windows Phone 8 upgrades.
Microsoft is attempting to make it up to current Windows Phone users with a Windows Phone 7 update (WP 7.8). It’s most noticeable change is a more user-friendly Start screen.
Users who buy Windows Phone 8-compatible devices, will be able to migrate their Windows Phone 7 apps. There's no backwards compatibility for the newly developed WP8 apps though and there's nothing that can be done about it.
This could mean a big loss of momentum for Microsoft’s mobile OS. They’re still the new kid on the block trying to establish a reputation. This isn’t helping.
