You know the drill. Apple issues an invite for an event, and tech media channels go wild with speculation. Except that we know the event in question this time, scheduled for March 9, is almost certainly about the Apple Watch. How? Well, we already know it's slated for an April release, so there's that. Oh and a not-so-subtle "spring forward" message the invite contains. Apple losing its cryptic touch? Maybe, but it's not unknown for Cook and crew to throw in a few surprises (but please, no more musical "surprises"). Engadget will of course be there to find out, with a liveblog so you can follow along too. Just don't forget to change your (non Apple) watch an hour, or you'll miss the whole darn thing.
