They announced that long ago. The stabilization level of XP is around a third with the benefit going to Windows 7. Even Microsoft has tossed a bone to those that won't be upgrading from Windows XP. They are going to keep supporting Microsoft Security Essentials and their malicious software scanning tool into Spring 2015.

This has been known for a long time too. There was tons of work in the Boston area doing corporate migrations last summer and fall. I think that a lot of that business is done and it was to 7; not 8 or 8.1. Who knows how long Microsoft will provide support for Windows 7 - I suspect that they will have the same difficult EOLing it as they did with Windows XP.
BTW, 95% of the worlds ATM use a Windows XP variant - Microsoft will have to support those terminals. I'm sure that they will charge a pretty penny for supporting them.
