When do you supports windows phone?

I have a few question, when unity supports windows phone? because n9(meego os) now supported by unity. i want to know if it is possible or not. if it is not possible, why?

For this to happen, Microsoft would need to allow Unity native access to the phone. Currently all 3rd party apps have to use Silverlight or XNA which just won’t work for Unity. I hope Microsoft gets smart and works with Unity on this because I think Windows Phone is a sleeper right now but has huge potential. Not to mention the upcoming Windows 8 tablets.
