EuroGamer is claiming to have even more details on the as-yet unannounced new iteration of the PSP, the PSP-4000.

Our development source today confirmed these reports, adding: “The screen is basically the same as the one in the 3000 – except it slides.” When ‘closed’, we were told, the screen won’t cover the entire face of the console, but the unit will be “significantly smaller in width” as a result.

With the console in its ‘closed’ state, most controls will be inaccessible. However, our source claims that games which use the shoulder buttons exclusively – such as LocoRoco – will be playable, as these inputs will still be accessible. It’s expected that the unit can also be used for media playback in this configuration.

All bets are that the worst kept secret in gaming history will be “unveiled” at this year’s E3. We’ll be keeping you posted.
