Sony is to officially announce the PSP2 on January 27 at a special press conference in Tokyo, according to reports.
Trade publication MCV claims that game publishers were informed late last year of Sony's PSP2 plans, which would hardly be a surprise seeing as the handheld has become a worse kept secret than PSPgo was ahead of its E3 unveiling in 2009.
A rear touch panel is one of a number of features repeatedly rumoured for the PSP2, and has been referenced by patents from Sony itself.
One of the titles supposedly in development for the new handheld is a version of Uncharted. That'd shift a few machines, we reckon.
