New Dura Ace 7800 SL wheels?

[Hereford Flyer]

Was just checking on the latest list of UCI aproved wheels and spotted a couple of new variations of the new DA 10sp wheels listed. A carbon tubular version and a clincher SL black alloy rimmed version of the 7800. Anyone know when these might be available or weights? Here is the UCI link:-
