VG247 has learnt that Sony is to reveal plans for PSN’s premium services at E3.

According to a highly-placed source, Sony will announce a large-scale monetizing scheme for PSN at the LA show, but we’re assured nothing planned will impact the service’s current free aspects.

A string of features will be revealed, apparently costing “less than £50 per year”.

Sony will confirm plans to give all subscribers one free PSN game per month, from a choice of “two to four” every month.

“If you work it out, PSN games cost an average of £6-9 each, so over a year you’re basically going to be breaking even,” said our source.

A streaming music application similar to Spotify will be announced in Sony’s press conference on June 15. It’s thought that this can run in the background while playing games.

Rumours that cross-game voice chat is being saved as a paid feature are apparently not true, we were told.

“I can tell you now, 100 percent, that that’s not the case,” our man continued.

“There’s nothing in the premium package which will gimp regular PSN users.”

The PSN premium services announcement is thought to be a major part of Sony’s E3 conference, which will also heavily feature Move.

It’s thought that a PSP2 announcement, for this reason, is unlikely, and will be saved for either gamescom or TGS later this year. Get more detail on that here.
