Nokia N810 upgrade with WiMAX leaked?

Shame on you Best Buy. Always jumping the gun on those misplaced ads before your supposed too. Oh, how we love you so. The leaked February edition of Best Buy’s online mobile buyer’s guide displays an assortment of sexy Nokia devices, but close inspection shows some odd details.

A device similar to the N810 is shown with a black case and an orange back lit keypad. There have been rumors floating around about a possible upgrade to the N810. Could this be a leaked peek at the N830 with a official unveiling at CTIA? This would be a perfect opportunity to introduce a new WiMAX device.
