The Japanese conglomerate corporation - who make various video games as well as the PlayStation consoles - had a press briefing at the annual gaming convention in the Los Angeles Convention Centre which ran from Tuesday (13.06.17) to Thursday (15.06.17), but have now said there are projects they "chose not to show".

PlayStation Worldwide Studios boss Shuhei Yoshida said in an interview with JagatPlay: "There are things we have held; [things] we chose not to show during this E3. Of course, there will be some more news coming out from our teams later this year."

One announcement Sony did make, however, was the second remake of beloved adventure game 'Shadow of the Colossus', which is expected to come to PlayStation 4 consoles in 2018.

The game was originally released over 10 years ago for the PlayStation 2, and the first updated version was released on the PlayStation 3 back in 2011.

At E3, the game was announced with a beautiful gameplay trailer that shows just how far video game visuals have come since the original release. From the video, the game appears to have many of its graphical and performance hitches evened out, in addition to sporting an overhaul in its general appearance.

Sony didn't say anything else about the game outside of its trailer, so it is not yet know how extensive the changes will be, although it has been confirmed that the story remains the same.

Meanwhile, last month it was reported that production of PlayStation 3 consoles has ceased, over a decade after it was first launched in 2006.

The console was usurped by the PlayStation 4 in 2013, and it is thought a new console, likely to be titled PlayStation 5, is coming in 2018.
