Its definately not a gift from Zaft since Kira is sending their mobile suits a one way ticket to space debris. I don't belive its even gonna be an upgrade. If you goto the official Destiny site its not even part of the archangel group and belongs to an other category. Its interesting. However from what I've seen there is going to be a second Justice and now possibly another Providence. So maybe Zaft makes it and Kira once again steals it?
