Looking at the complete laps of releases since Gundam Battle Universe (1 additional artdink game, 1 additional Gundam Vs Gundam game) vs the higher priority for release that the Macross games have recieved, I'm gonna have to disagree with you on a sales front. Hell, Trial Frontier is the first ArtDink game to hit PS3, that alone says a lot. Bottom line is, money would be the big dictator for release order, and the Macross PSP games seem to be stealing the limelight away from the Gundam PSP games.
