Later this week, on January 27, Sony is holding an event where it's widely believed that the oft-rumored successor to the PSP will be officially unveiled. But, as is so often the case, it looks like some of the details have been leaked before the big announcement.

According to Japanese newspaper Nikkei, via Kotaku, the PSP2 will have 3G capabilities and will be able to connect to the NTT DoCoMo network, which is one of the largest cell phone providers in Japan. There's no word yet on whether or not any Western providers have pledged their support.

In terms of hardware, the report claims that the PSP2 will feature an OLED touchscreen. OLED screens are brighter and provide better and wider viewing angles, but also have a shorter lifespan compared to LED or LCD screens. Sony has already implemented OLED touchscreens in some of its other products, including the CyberShot line of digital cameras, so this doesn't seem too far-fetched.

It's all rumor for now, of course, but we'll likely learn just what the PSP2 is and what it can do on Thursday. Will it be enough to compete with the Nintendo 3DS? And how will the PSP2 compare to the rumored PlayStation phone? Hopefully, we'll get those answers soon.
