PlayStation Worldwide Studios boss Shuhei Yoshida, who oversees all game development at Sony, has teased that Sony's E3 briefing in June will be one you won't want to miss.

"Some of the things that we are preparing for E3 are very, very exciting," Yoshida told GameSpot in a recent interview.

He went on to note that Sony is in the process of shaping its plans for what it will--and won't--show during the press conference, expected to be held on Monday, June 9.

Sony has kept quite mum about its plans for E3 so far, but Microsoft has been much more eager to boast about its conference. Just this week, Head of Xbox Phil Spencer promised games, not hype for Microsoft's showing. And before that, he said Microsoft's briefing will be 90 minutes long and that it won't feature many executives.

Earlier this week, Sony trademarked new games called Kill Strain and Entwined. These games have not been announced, leading some to believe they are projects that Sony might unveil at E3.
