SP3 of XP?

Now confirmed is a Service Pack 3 of Windows XP, scheduled to ship after Vista has gone gold, around Christmas of '06.

Why?

I swear this is going to make my workload heavier, since I'm going to have to accommodate clients who would want to extend XP beyond, God forbid, '08.

And test, validate, and implement it.

Woe, O Woe!
