It's no wonder that Sony has been eyening the success Microsoft have had with their Xbox Live, and there has been a lot of rumours that Sony would consider adding a price themselves. If we are to trust VG247, Sony will be showing a PSN Premium during their press conference at E3.
This premium version of the Playstation Network is supposed to cost less than £50 for a year, and would include a free PSN game every month. The plan is not to "gimp regular PSN users," according to VG247's source. A streaming music service, similar to Spotify, is planned as well.
True or not? E3 is coming up in only a few weeks, so we'll just have to see!
