U400 Deluxe (Black) seems to be completely sold out via Apple Store

Was looking to purchase the U400 Deluxe (Black) from the Apple store, and the availability seems to have changed from mid-April to now being completely unavailable. Does anyone think this will be restocked at some point? Or is it going to no longer be available from them?
