No doubt I would love and need more vault space, but it just wont happen. Its not a choice Bungie made, its that PS3 and 360 simply cannot support it. They just dont have enough RAM. And if youre wondering why they couldnt just add it to PS4 and XB1, its because your data is synced on your platform. Meaning that what you do on PS4 will be saved on PS3 where you can continue where you left off. So, if we have a 36 space vault on PS3 and 100 space vault on PS4, it wouldnt work. All of your weapons would get deleted because PS3 cannot support it.
