Successor / alternatives to 2D XNA?

It looks like Microsoft is backing away from XNA (but not DirectX): (see http://www.zdnet.com/microsoft-false-alarm-we-arent-backing-away-from-directx-7000010647/, note that there is no XNA Game Studio / XNA available for the new Visual Studio 2012, etc). What technology can be used in it's place, for a 2D, managed game on Windows? I'd love to find something that works on Windows 7 and 8, with bonus points for WinXP and/or WinPhone. I apologize for the overly broad question, but I've dug around in the MS website & can't seem to find any clear guidance. Silverlight looks promising, but I can't tell if that's going to be phased out too. It looks like Metro apps should prefer to use JavaScript, but I can't tell if you can use C#/.Net with that. WinForms would be great, but I think that's also "the past, not the future" Any guidance would be most appreciated!
