52 is kind of a cool choice. I liked that Zeiss did 54s, although was always disappointed that they didn't make 15s. I would similarly be disappointed if Swarovski did not make 15s. But, the prospect of 12x52s is exciting to me. I have had a 12 size hole in my binocular collection for a long time. The 12x42s never really excited me for whatever reason.
