Nope no love here for SA hubs...yeah right! Last count; there are a grand total of 23 IGH bikes and only 2 of them currently sport Shimano
Most of my hubs are the nearly indestructible AW or it's generator counterpart the AG. I have a couple of FG series hubs too. I just built up a set of wheels using the modern X-RD5 and the XL-FDD for my son's city bike.
I have not seen ANY IGH bikes in my LBS's
and there are not many bikes available on the NA market with IGH, but it is getting better.
