I just got the shipping notification today and it says they will both arrive on Thursday the 8th. Initially it said they would not arrive until the 20th so I am happily surprised.
Yeah, I got my dock shipping notice today as well. Interesting however because I didn't order it until just last week. I ordered the case on the first day of pre-orders, but no word of it yet.
I had a similar experience. I ordered 2 docks with my iPad and then last week ordered a third. I have tracking info for the one I ordered last week but the 2 I ordered at the same time as the iPad haven't shipped yet. No big deal, just kind of strange.
