There have been multiple rumors for quite some time regarding the premium PSN service ever since Sony has announced that they were strongly considering the idea. There is now talks that the Premium Service will be called PSN+ and details about the service will be told at the E3 convention in June next month The rumor says that some of the things mentioned in the survey that was conducted a while back will be features.
Some features that are rumored to be in this service is access to a list of annually changing content like Minis, PS1 Classics, and DLC for games. You will also be able to get discounts for games in the PlayStation Store. Also an extended demo sort of feature that gives you the ability to play a game for one full hour and you will be asked if you want to buy it from there.
While subscribed, you will also be part of the PS3 Protection Plan, PlayStation’s warranty program that was unveiled a few weeks ago. Users will also be able to get patched downloaded in the background for games they have recently played. Remember that these are just rumors and should not be taken seriously until confirmed (but, after all, this is a rumor about Sony).
On a related note, Sony Europe boss Andrew House said very recently that they were still seriously considering a premium service for PSN and reminded that the features on PSN now will still remain free.
