It's a big strategic mistake Microsoft committed when they launched Windows Phone 8 while it is incompatible with Windows Phone 7.
WP7 had been in the market just less than a year.
Users who are stuck with Windows Phone 7 devices are not able to upgrade and having this experience at the time they switch to a new device there is a good chance they don't purchase another WP. There are still many WP7 devices in stock and on the market and dealers have to get rid of them before they start to sell superior WP8 devices. Finally WP developers can't be happy since they have to purchase another device and maintain both versions.
Microsoft should have launched it in December 2012 instead of September 2012 but make it fully backward compatible.
