I just saw an item WR-A10 among Nikon's accessories. It converts the 10 pin socket to something Nikon is calling a new "Accessory Terminal", which appears to be a flat strip-like socket. So does this mark the end of the much-loathed round 10-pin socket? Any more info anyone can add? Like does the new terminal support more functions or have more pins? Too much to hope that it's based on an industry standard socket. A search on Nikon UK's site for "accessory terminal" turned up nothing, not even the WR-A10. Edit: At the cheeky price Nikon is asking for this simple adapter, I can see 3rd party knock-offs being tooled up for in China right now.
