All you guys saying it doesn't matter obviously don't know how stock markets and shareholders work.
Has Sony had any major negative consequences since they missed their PS4 forecast a couple years ago? Nope.
Hardware forecast is only one part of the equation, if hardware slightly misses but software, revenue & profit exceed their forcast than shareholders aren't going to go in a frenzy.
When the herd loses its way, the shepard must kill the bull that leads them astray.
