For quite a while there’s been several hints at Sony revamping the Playstation Plus program. These were mostly in the form of surveys outlining different plans, which included more disc games or more recently released games. Sadly the surveys seemed to have no impact, but it seems Sony plans on changing the program come E3.
With an update to Sony’s official site, it seems the future of Playstation Plus will be revealed tomorrow at E3. Sadly no further details are known, but this could lead to some Vita related content.
