The information, provided by an attending "source", included plans to be "more competitive" with PS3 pricing from March 2009.
Sony Europe boss David Reeves is also alleged to have said there will be technical innovations to come for both PS3 and PSP, although no details were given.
The source claims to have seen footage of Uncharted 2 and God of War 3 for the PlayStation 3, and LittleBigPlanet on PSP, which it's claimed Media Molecule has been working on for four months. According to the report, target footage of MotorStorm PSP was also shown.
Although Sony has repeatedly stated there will be no price cut for PlayStation 3 hardware this year, a price reduction in March in time for the Easter sales isn't far-fetched.
And before the release of the PlayStation 3 version of LittleBigPlanet, Media Molecule's co-founder Mark Healey told GamesIndustry.biz that "there's definitely scope for a PSP version," sparking rumours of a handheld Sackboy game.
