XP Pro. The end is nigh (30th June) and support

Windows XP reaches its sell-by date in a few days (with the exception of XP Home "either June 30, 2010, or one year after the general availability of the next version of Windows"). lifecycle/default.mspx

Mainstream support ends 4/14/2009. That's only 10 months full support left ! Extended support ends 4/8/2014. Which is security fixes only, no new versions of browsers, media players or support for newer products (eg though, doubtful, next version of office might not support XP due to using a Vista only feature that will not get backported to XP).

Even with XP SP3 only recently been released, Microsoft clearly states: "When support for a product ends, support of the service packs for that product will also end." support.microsoft.com/default.aspx?scid=fh%3Ben-us%3Blifecycle&LN=EN-US&x=20&y=10#Service%20Pack%20Support

Will XP's extended support be enough for those who want to continue using XP ?

Will people who intially dismissed Vista, consider upgrading to Vista in the near future ?

Or will people who do not want to or cannot (eg people with ultra portable and sub notebooks) use Vista yet, hold out with XP until the next version of Windows is out in 2010 ?

Or will people start migrating away from Vista to Mac or Linux ?

I have always been a fan of Linux, and if I wanted to move to Linux 100% tomorrow (I am currently happy with XP though). I have 3 personal machines that do not meet the specification to run Vista and have no need to upgrade them to anything faster, so upgrading to Vista is not an option. So I still need to decide to keep XP until Windows 7 comes out or move at-least partially to Linux.
