Well said. There will definitely be a Platinum Edition to cater to those elite who prefer silver. I think they'd go Platinum over white gold, just because Jony Ive would prefer to say the word Platinum.
There will be anodized gold Sport to match the iPhone. And there will absolutely be a $1k-2k gold clad option. Perhaps Vermeil, perhaps. Since Rubedo is Patented and Trademarked, I can see Apple coming up with their own solution. They could easily do $14k gold, but I see them creating a new alloy, or "plating" process that is superior to anything that exists today.
The Edition will be distinguished by its custom bands, and accents like the red and white digital crown dots. The Edition will only be offered in the current body style, whereas the sport and stainless may be offered in last years design at a price.
I'm expecting the new gold Sport & Stainless, and Platinum Edition to be offered by Christmas, along with a host of new bands for holiday gift giving. New gen 2 designs by Spring -- maybe even round.
