I'm just interested in what happens for Blue. Windows Blue seems to be a great evolution of Windows 8 that addresses many major complaints, I hope Windows Phone Blue will be the same thing.
It's slightly disheartening that there's no notification centre spotted in Windows Blue, it really needs to be a feature implemented sooner than later because it's a developer thing. Microsoft can delay other solely user-facing features because they can be implemented at any time, but getting the notification centre out there sooner means more applications than will support it sooner.
