Something is going on at every company.
You know what? I'm out. This is all it's going to be. Kneejerking here and there, Sony is doomed, what happened, something is up, panic.jpg (or .gif), and many people will blow this out of proportion as if they've never seen key figures leave a company before, as if it never happened prior to this generation or the previous one.
You do realize there's a middle ground right? Its kind of weird for two game directors to leave a project thats pretty far away from shipping. It can be weird without being "ps4 is over, Sony is done."
