UPDATE 10-15-12
As far as I have found out Windows 8 will continue to sell and link to Xbox live games.  Similar to i pads and the ability to use and purchase apps directly.  To the best of my knowledge, I think that Microsoft will continue to have Xbox live.  But they want to sue DirectX11, so they will have to tweak the C#/xna pipeline, or move on to something else.  C++ .... I feel that if they continue in either of those veins, It will not be a problem.  I understand the Math and general algorithm I need for my projects, and this is something that would happen to me eventually after I graduate.  Whether because of a new software, or a new console, I'll have to be flexible.  This is just a taste, but I am ready for it. 
But I am still searching for conformation. 

I'm looking for a page that basically says that Windows 8 does not support .xna ... yet  :)  IF anyone has any information, or an article, please send it to me.  I'd greatly appreciate it.  I'll update this as soon as I find out more.
