It would be cool if you can transfer 360 to ps4 or ps3 to xbox one and others BUT PlayStation and xbox are way different things and support other things because xbox saves games by your account and so does PlayStation but they dont support each other. I mean if they were the same company things could work out but the thing is everything is saved in YOUR account not bungie.net. The only solution that could make it where they can do this (360 to ps4) or (ps3 to xbox one) is if only made you login with a BUNGIE ACCOUNT <------ do it bungie pls its so easy make them do a account for each accouny
