The art was usable for the Marauder in the pre alpha. I’m pretty sure that if they decide to insert them in the game, they just need to flip a switch in the code. With patience, I honestly think we’ll see thMarauder and Whammy released in the next few months.
However, the other three Phoenix mechs in MWO haven’t been animated by HBS. The Phoenix Hawk, Rifleman; and Archer. I wouldn’t expect to see those until a sequel at best, which is a shame. 45 ton 6/9/6, 60 ton 4/6, and 70 ton missile boat would fill some holes in the game.
