What is the best way to cast a shadow of doubt on a shiny new product? Why apply a noticeable price cut barely two weeks after its launch, of course! That may be the effect of Sony's sudden change in the price of its Xperia X flagship in the US. Not that a lower price tag is actually a bad thing. And it wouldn't really be bad if it were part of some launch promo. But given the length of time that has passed, the almost unexpected move does bring up questions of whether it was done in order to save the Xperia X from a disastrous fate.
