you have unlimited potion as long as you continue paying your vip subscription. you get this along with a vip only item each month and more color options for customization. this saves you plenty of gralats from uploading a custom body that has the color you want in it for 20k and you don't have to buy unlimited rev anymore. The unlimited ammo probably wont be implemented because you can just get ammo free as is. 7.5k isn't that hard to make in iEra anyways, just 5 hours of jobs will get you around that, and if you base or PK then you are all set pretty much with body parts.
