"Coming Soon" Motorola said when they announced the new wooden backs for Moto X. Now they have removed these two words as wooden backs are now available for Moto X for $25 extra.
Moto X is available in ebony, teak, walnut, and bamboo backs in the wooden series. These backs are still surrounded by plastic so make sure to match the colors otherwise the device will look odd. Anyhow head over to Moto Maker if you want to buy one wand the device will be shipped to you in six day time span.
