I don't know where the problem should be.
Sony was focused on ps4.
they neither wasted too much time for vita nor for ps3(some may remember that's the system that sold almost 80 mio units and is far away from dying)
a big announcement for ps3/vita would have been ignored by most people as everyone is waiting for the ps4(design,games).Announcing something really new and great for ps3 and vita would be a waste of potential as you can't create a hype for a new vita game when people are focused on ps4.
As MS new surveillance system PK was not overwhelming but good in terms of quantity(too many unknown factors too judge the quality) Sony needed a good response.
