AppleTV Delayed Til March: Aaand the Hold Up Is?

AppleTV is delayed until mid March. We knew this...but then we didn't. Now it's officially late. Lynn Fox, Director of Mac PR, says:

Wrapping up Apple TV is taking a few weeks longer than we projected
So what's the hold up? The device looked pretty ready to go a few weeks ago. Are they having trouble putting together the device as we saw it? Or, are they readying One More Thing?

Either way, I really miss the days when an Apple product was in the store the day of the announcement
