My guess is it'll be around as the most up-to-date Windows on the market for about 4 years. It'll take some time to overtake Windows7 which it will inevitably do, and in much the same way that Windows7 has just done.

People make a big song and dance about WindowsXP having a longer life than other Windows' but people forget that Windows XP SP2 is COMPLETELY DIFFERENT to Windows XP vanilla. The progression of OS's is really much more like:

Windows 95 (lasted about 4 years)
Windows 98 (lasted about 4 years)
Windows 2000 (lasted about 4 years)
Windows XP vanilla (lasted about 4 years)
Windows XP SP2 (lasted about 4 years)
Windows Vista (lasted about 4 years)
Windows 7 (currently holding at 2 years)
Windows 8 

where is Windows ME? Windows 2000 is only for business, like NT.
