Yes, but conditoinally. As of current, your original pilot character doesn't maintain any stat changes, but your mecha retain all tune points. "however," you can't actually use all those tune points, until you unlock the stat limiter in the new game, and you sitll have to unlock the mecha itself all over again. As for new mecha, you get a certain amount of bonus tune points for each mecha, for each previous gundam game save you have at the start, which is a definate plus. I'm hoping they elaborate on this to include show character stats & love/respect levels.
