Sony has not yet announced anything about a successor to the PSP, but games developer NetherRealm has supposedly seen the device and describes it as being "pretty powerful".

Adding substance to existing internet rumours about the 'PSP2', the studio behind the upcoming Mortal Kombat game has reportedly already had plenty of hands-on time with the new handheld console, according to executive producer Shaun Himmerick.

Predictably, Sony is keeping schtum and refusing to confirm the existence of the PSP2, so we'll all just have to wait and see.

We'll bring you more news as soon as we have it.
