Sony has managed to hold its own in the portable gaming market, and even though it never had a reasonable chance of overthrowing the DS, the PSP has done well enough that it is widely considered there will be a successor, and it might have a connectivity edge over the 3DS.
Sony has confirmed previously that it has no plans to bring 3D gaming to the next PSP, however if Japanese analyst group NTT DoCoMo knows what it's talking about, there could be something else that sets the PSP 2 apart: a 3G connection.
3G is the wireless network that most smartphones currently use to connect to the Internet. The appeal of being connected anytime, anywhere has also brought 3G into devices such as the iPad, the Kindle, and portable Internet hotspots known as "MiFi"s.
In a Wall Street Journal report, NTT DoCoMo says that bringing 3G into portable gaming is the next logical step, and that both Sony and Nintendo could stand to profit from introducing such a feature.
Of the two, Sony would be the more likely candidate, as Nintendo has a history of resisting advancement in Internet connectivity.
Little is known about the PSP 2 at this point - we don't even know if it is real at this point. However, the ability to download games, send messages to friends, or even cooler, connect remotely to a PS3, would be a huge value to gamers on the go.
