Im very interested in the new PW units - however when I asked the local Nikon dealer about the CLS availability they said probably never! I invested in Nikon CLS and have 2 SB-600, 1 SB-800, 2 SB-900 and 2 SU-800 units. I also have a photogenic studio strobe that I have attempted to use with the Nikon CLS strobes - with very mixed results. The Nikon CLS system is superb when it works! However using todays standard PW to fire them disables the CLS and requires manual settings for each strobe, so I have been waiting for a way to combine both CLS and non-CLS - as well as extend the range and dependability of CLS in demanding situations. Keep us posted!
