Sony has suggested that some surprises lay in wait for those attending August's Gamescom 2013.
It was revealed at E3 earlier this month that Sony has 30 games in development for PS4, 20 of which are due for release within the console's first year. 12 of these are new IPs.
But speaking to Gamereactor (as spotted by CVG), SCEE CEO Jim Ryan stated: "We very consciously at the [PS4 reveal] event in New York on February 20 showed a lot of software, a lot of first party software. What we did at E3 was really show some updates to those games and introduce The Order 1886.
"There's a lot [of games] coming. There's a lot going on, it's just that we need to keep stuff back. We've got Gamescom for us Europeans and we need something to show at Gamescom."
Gamescom 2013 kicks off on August 21st in Cologne.
