Sony unveiled a couple of screen-shots of the April update of the Playstation store.

The Playstation Store revamp comes in response to a survey last year which showed that many PLAYSTATION Store users wanted a better interface and easier navigation. The new design will deliver a hugely improved navigation system, much greater scope for categorization and a dynamic new user interface.
Content will be suspended for two weeks while the improvements are carried out but you can look forward to a special update in mid-April.
There will be no weekly content updates between now and the re-launch, although users can still download content from the back catalogue, such as Warhawk and Gran Turismo 5 Prologue.
See the new design in the story gallery.
