Just got off the phone with Mavic, to get an RA# for my damaged rim, they are currently out of stock on EX823's and don't know if they will be getting anymore in until the new UST rims arrive for 05, I don't know when that will be. From my guess they are aware of all the issues the current 823 rims are having and Mavic seems to be making changes, we'll have to wait & see. As far as what they look like and the specs, your guess is as good as mine. Just thought I'd pass on this little bit of info I just got.
