As far as seeing LTDs as buyer's premiums, don't count on it. They've explicitly said this was the only opportunity to get it as a premium - future decks will be contest prizes and the like, unless they decide to go back on what they said.
As interesting as this deck would look in different colors, I don't see it happening. They didn't make a red Artifice v2 because they didn't want to dilute the value of the v1 release, so they have an appreciation for some of the points Lordlupus was making. At best, they'd release an "UnLTD deck" of a similar design, and maybe do that in colors.
