Oops, I need to correct myself on that; I was misled by glancing at tiny photos. If you search as I did for "SLC 56", B&H does display the previous Neu/WB 8x56 (and 15x) as "No longer available". But just as Robert said, the current 10x56 is available there now (along with the 15x), while the 8x is listed as "Discontinued", which indeed sounds odd. Apparently that doesn't mean by the manufacturer, but B&H. (Gordon, proudpapa56 here, is still selling all three.)
I finally decided to get the 15x to go with my 10x (thanks again Gordon!) and couldn't be more pleased. It's surprisingly easy for me (and my SO) to use handheld, and has been out to the local lake twice already, very handy for identification at greater distances. These SLCs are my favorite binocular today, when I can carry something full-sized instead of a 10x32.
