No confirmation of the Dark variants, but they may come as well.
Retail listing have begun to appear for standalone versions of a couple of rare toys.
GameStop is having a "Skylanders Day" this Saturday (January 9) in which packages containing the Donkey Kong and Bowser figures, along with their figures, will be sold separately for $24.99. The figures are expected to appear at other stores around the same time, and some have already appeared on store shelves.
Although the Dark variants of the figures are not usually sold separately, GameStop will be selling an exclusive Kaos Trophy ($7.99) which has been previously exclusive to the Dark starter packs. Listings for the Dark packs have also appeared at multiple retailers including Amazon and Toys 'R Us.
The Skylanders Day will also have offers where buying a Starter Pack ($39.99 for regular, $60 for Dark) will get a previous Skylanders starter pack free, a buy one get one free on SuperChargers figures, and discounts on select figures.
