As a retailer, the fine folks at Gray’s aren’t privy to information not available to other retailers. I suspect Becky may have spoken inaccurately.Gray's in London are usually reliably informed by Nikon UK, which is why I take the sound bite seriously in their above video. Nikon's subsidiaries, including Nikon USA are not necessarily in the know about arcane technical details.
Unfortunately, I’ve had frustrating experience with getting accurate answers to thorny questions from customer service at both Nikon UK and Nikon USA.
No matter, though. All will be clear in the coming weeks.
