Sony will hold a meeting on the 27th January in Tokyo to discuss "business [overview] and strategy".
That's already confirmed by Joystiq. But we don't know whether the MCV and VG247's sources are right.
They claim that this meeting will be the launch for the new PSP2.
According to Sony it's no major trade debut, just a Tokyo meeting [of unknown spectacle]. But then again the 3DS unveil was a normal random press release.
Guess we'll have to wait until then.
