Yes, I've heard that the rose gold was Japan only, so it was very limited!yes, you can do that and reissues will be comming out w new colors soon so you might like them bette, just get what you like better between the two. Dark silver is more common -- they were re-released again this yr thats why there are more people using it. Im not even sure when the rose gold came out, i got mine from a resellerr -- mint condition, and the receipt says it from japan.
The reissue is coming back in a color called "pewter" which will replace the dark silver. This color is different and is a truer dark silver color and has none of the bronzy undertones that the currently existing dark silver has. Personally, I adore the color of the current dark silver! Most perfect metallic ever, hands down IMO.
