I haven't heard anything yet!! But I'm definitely starting to obsess too. I've been working on FAFSA - we have to figure out our 2006 tax stuff to fill out FAFSA, so I'm thinking about that as busy work to do in the meantime, to keep me from dwelling on what schools might accept me, etc.
My friend Peter went through this process last year (applied to PhD English programs) and said he didn't hear anything until *late* March. He didn't apply to as many schools as me, but still - LATE March?? Gahh. I swear most of the schools said mid-March...didn't they??
*succumbs to obsessing*
