Don’t fret, actual phone support will be good through 2014. However, EOL is scheduled for July 13, 2010. Along with XP SP2, Windows 2000 Server will join the party.
It’s OK though. Windows 7 is the new XP and Vista is gone. I assure you that once you go 7, you won’t need to go back. Even if you do have to go back, depending on which version of 7 you get, you’ll have a virtual XP anyway.
