Considering the JJP site clearly listed 3 different prices ($8000, $8500, and $9000) and 3 different models for Hobbit .... here seem to be the only (likely) possibilities:
1) The $8500 version is the "limited edition" that current pre-orders represent. The $9000 version is this new "Gold Smaug Edition" and current pre-orders will have the option to upgrade either for a reduced fee or possibly even for free
Note: It still remains to be revealed whether this new "Gold Smaug Edition" will be a "limited" edition or just a "special" unlimited edition.
2) The $9000 "Gold Smaug Edition" is now the "limited" edition and is what all current pre-orders will be getting. The $8500 version with the artwork already shown becomes a "special" edition with powder coating over the "standard" edition which will just be brushed chrome.
Option 1 seems the most likely since, IF JJP is close to selling out the LE's, what would be the point of raising (or listing) the price to $9K now (as noted in option 2).
All I know is ... if I was expecting to have a "Limited" edition of a game, I would think that edition would be the deluxe, high-end, and more expensive version (and fewest made too.) It seems crazy to me that JJP would once again introduce another new model above the "limited" edition model. Can't wait for how this gets spun tonight.
