It's been quite a while, three years in fact, since we've last seen a P series smartphone. In fact, there has actually only been one member of that family, until now. At least, if this latest leak is to believed. The rather strange thing about this Xperia P2 is not that it exists, considering how the Xperia P wasn't exactly a hit. It is the fact that its spec sheet make it look like a thicker variant of the just announced Xperia Z4, a smartphone that itself is still shrouded in mystery, that makes it rather curious.
