''The source also mentioned that the following publishers will be on stage: Rockstar (with Grand Theft Auto), Ubisoft, Electronic Arts, Konami, Capcom, Warner Bros, Activision, Square Enix, Take Two.
There will also big titles announced for the Instant Game Collection, a segment on Project Morpheus, one on the Sony Entertainment Network and a re-introduction of PlayStation Now. Price drops will also be unveiled for the PS3 and PS Vita.
We’ll also see several smaller-scale, downloadable titles. PS Vita Vita will get some attention, but not much – as it’ll be a PS4 show. PS3 will get a montage and few new titles. Finally, the show will close with a teaser of a sequel of The Last of Us.
Again, everything mentioned above should be taken with the skepticism usually reserved to rumors, but much of it is so specific that it’s hard to completely disbelieve it. Unfortunately we’ll have to wait for June to see if everything will check out, but one thing is for sure: Personally I really hope it will, because if this is really what Sony’s presser will look like, we’re in for a real treat.''

(Update: our source followed up saying that he’s actually not 100% sure if Rockstar will actually be on stage or Sony will just announce the next generation Ground Theft Auto V on their behalf)
