Well the Rumor is that they are going to let you retain with just a Plus membership which is free. I don't believe that has been implemented yet, but it makes a ton of sense. One huge selling point for premium is the exclusive games, they figure most people won't be dedicated enough to download everything they want, nor have the storage for it. I already feel like I need an eagle eye to look out for titles before they disappear, there have been a handful of times I looked up a game that I just found out about and realized they just removed it from premium last month and it is now 29.99
