PlayStation 4K, PlayStation VR, and oh yeah, maybe some games, too.
Before E3 starts properly on Tuesday, Sony will unveil its plans for the show at a press conference from Los Angeles' Shrine Auditorium. Ars will be on hand to liveblog the event at 6pm PDT (9pm EDT; 2am Tuesday UK time) on Monday, June 13.

The big rumors surrounding Sony ahead of E3 this year have all swirled around an expected "PlayStation 4K" mid-cycle update for the PlayStation 4 hardware. Sony confirmed those reports just days ago but said the hardware wouldn't be ready to be shown at E3.
That leaves the upcoming PlayStation VR headset as the sole likely hardware focus for the press conference. This is the final E3 before Sony finally releases its PlayStation VR hardware to the masses, so expect an intense push to show off the potential of living room VR. There will probably be showcases for some of the software that will launch alongside it this October.

On the software side, expect news on previously announced games like Horizon: Zero Dawn and Detroit: Become Human. Sony will also likely talk up Destiny and its upcoming expansion (even though that game is also on the Xbox One). As far as new exclusives, we've heard rumors that a new God of War titles may be in the works. And Metal Gear Solid creator Hideo Kojima, newly free of Konami and working on a PS4 console exclusive, could make an appearance as well...
