From the looks of it, it looks like both the Xperia P and Xperia Sola is about to hit the retail channels. Sony Mobile Russia has unboxed both of these two devices on Youtube.
The Xperia P will come with the EP850 charger, HDMI cable, a set of SmartTags and a stereo headset (MH750). The Xperia sola will come with the EP800 charger, MH750 headset, NFC SmartTags and USB cable. See the videos below (both in Russia).
