We're not quite sure just how based in reality this is, but what you see in the promo video above is the Samsung Omnia Pro B7610, though different than what we've previously seen.
Strange things can happen in promo videos. Occasionally they let loose a juicy morsel that ends up being an unreleased device. Other times they're just made-up images. Our guess here? An Omnia Pro in a slightly different shell.
