The previous Wireless Alum. Keyboard was model MB167LL/A. The one on Apple's site is now MC184LL/A complete with wiped reviews (I think there is one now). Anyone hear about this? Is there anything different about it? Maybe an improved BT antenna to go with the theme of the other devices that were updated? edit: someone beat me to it I suppose, but didn't state it was the wireless so I didn't see it at first. 2 batteries now I suppose.
