Sony's PR team must have accidentally eaten something with hallucinogenic properties because their latest video ad is very bizarre. It obviously contains images related to Google's newest OS, Android 5 Lollipop, but the other images might take psychiatrist to actually interpret. We suspect this is a teaser trailer for their latest flagship device, the Xperia Z4, which is likely being announced before CES or MWC in 2015. Of course, that's purely speculation on our part. What's your perspective?
