Got an e-mail this morning from Koko at LB, following up on an inquiry from before I bought my AR56 wheelset, that the new AR55 Pro rims (in standard and flyweight) are beginning production now. Pricing for the rim only is $259 and $271 respectively. Not on the site yet, that I could find, but if anyone is interested, might be worth an e-mail. No specs were provided in terms of width (int/ext) or weight.
