Surface Pro 2 docks available

I just got an email that said they're already available. I thought it wasn't going to be released till 2014?

Either way, I placed my order, and it seems to be in stock and ready to ship. They might be available at stores now, too.

I think the dock is the final piece that really realizes Microsoft's vision with the Pro - a powerful tablet, laptop and desktop, all in one.
