Unfortunately, the April fool's day prank will be on all those people who don't run Windows Update and there probably won't be any good news on April 1. April 2nd will probably full of announcements that were deferred by a day to avoid being mistaken as a joke.
Of course, being in New Zealand, we experience any effects of date related issues first (viruses, worms or product bugs) but then we get to put April 1 behind us while you are still worrying about it. I'll let you all know if we survive ;-)
