PlayStation 4 could be revealed as early as May, a Sony executive has teased.

Talking to Spanish website during last week's CES (translated by Google), Sony Home Entertainment's vice-president Hiroshi Sakatomi revealed that details around a next-generation PlayStation were "still a big secret, but our friends are preparing Sony PlayStation.

"I can only say that we are focused on the E3 gaming event, scheduled for June. [The] announcement may be in that minute or even earlier in May."

Pushed as to whether Sony's reveal would be a major announcement for the firm or a minor reveal, Sakatomi stated: "Probably the first. In that time we expect to deliver great news, but we must wait until May at least."

PlayStation 4, heavily rumoured to be codenamed 'Orbis', is rumoured to include a four-core AMD x86 3.2GHz processor, 2-4GB DDR 5 RAM and an AMD 8000 series GPU. The console is expected to launch in late 2013 or early 2014.

A report back in July revealed that Sony has been developing a next-generation PlayStation since at least August 2010.
