You have to assume, having seen the trailer, that the Frontier is the 11th Macross class colony ship, not the 11th "Super Long Distance Emigration Fleet". That would make it a Megaroad class. The numbers don't jive. And then we have the issue of 10 million colonists, which is WAY over what both class ships can hold. According to the Compendium, Megaroad class ships held 80,000 colonists, with the Macross class (the 7, atleast) holding 350,000. I guess this is where those colony pods that we see in the trailer would fit in. Which again makes it a Macross class colony ship.
