There's a Dark Templar vote on the StarCraft II Website, asking you to be the decider, offering visitors the chance to vote on which of two versions of the Dark Templar unit to add to the RTS sequel, either the Lenassa or the Zer'atai tribe. They have movies of the units to help you choose, and also offer a third option that we suspect might be the winner: "The third and final option is to have both tribes represented: When you build a dark templar, either the Lenassa or Zer'atai dark templar would spawn randomly." Thanks Shacknews.
