Will the skins be purchasable separately? I have the 'Snowblind' skin but like the others as well. However, I don't want to buy another vehicle.

The skins are unique to Warbond SKUs. Concierge members get access to the Dunestalker Skin and all backers get access to the Snowblind skin. These-limited time offerings will not be able to be pledged for separately.
