Microsoft officially announced it will no longer develop new features and hardware for the Windows Phone. As most things official are now announced via a tweet, we refer to the tweet by Joe Belfiore of Microsoft:
"Of course we'll continue to support the platform.. bug fixes, security updates, etc. But building new features/hw aren't the focus."
Not much development has been happening on the Microsoft Mobile OS for about a year now, but Microsoft hasn't released any open statements on it.
The problem was, the Windows phone market was just too small for most organizations to commit resources developing for the platform. Microsoft did everything they could to encourage developers to write Windows apps. “We have tried very hard to incent app devs,” explains Belfiore. “Paid money.. wrote apps 4 them.. but volume of users is too low for most companies to invest.”
Belfiore switched to Android, as did Bill Gates. And now they focus their energy on developing Microsoft products for Android and iOS instead.
