See, console manufactorers don't hate and fight as much as we want to believe. It's only the fanbases who jump at each other, meanwhile Sony offered Nintendo the handheld market monopoly on a silver plate and now slowly retreats from their home turf step by step. That's true generosity!
What? Sony loses two times for Nintendo in handheld. Besides all major thirds supports Sony devices. In handheld space, Nintendo never loses.
