Ultimately it was the games. The PSP did fine despite it's price, but it had a great line up of exclusives backing it. The Vita on the other hand has relatively few, with it's highest rated game being a PS2 port :/ The loss of monster hunter also played a lot into it. That was pretty much the PSP's counter to Pokemon in Japan.
It's a shame really. The Vita is an amazing piece of hardware.
