You know who knows everything? People familiar with the matter. In particular, they know everything when "the matter" happens to be Sony's handheld strategy for 2010, which is said to finally include an honest-to-goodness PSP with phone capabilities -- something the world's been demanding for as long as they've wanted a Zunephone. According to the WSJ, the device is apparently part of a larger push by Sony to create an iTunes-like Utopian ecosystem of products this year that connect to Sony Online Service, an ecosystem that would also include a hybrid portable of some sort that "blurs distinctions among a netbook, an e-reader and a PlayStation Portable." Details aren't offered on this particular monster -- but turning our attention back to the phone for a second, it's claimed that Sony's working with it in conjunction with the folks at Sony Ericsson under the direction of Kunimasa Suzuki, an exec largely responsible for the VAIO line who's also involved with the PlayStation team. Of course, SE's already taken some baby steps toward corporate harmony by bundling Remote Play support with the Aino, but everyone knows that PSP compatibility is the panacea; Microsoft finally buckled on the Zunephone thing with the introduction of Windows Phone 7 Series, and there's no reason why Sony shouldn't follow suit.
