Sony will upgrade its PS3 console in the autumn with bigger hard drives. The announcement was made at the gamescom video games conference in Cologne.
The existing 250GB model will be replaced by a 320GB version which will be sold as an exclusive PlayStation Move bundle costing £284.88.
From October the 120GB model will be phased out and replaced by a 160GB version which will cost £249.99, the same price as the original.
Sony said the extra storage was being offered because of the increase in downloadable games and films.
It was confirmed that the PlayStation Move, Sony's new motion control offering, will be released in the UK on 15 September.
