Technically, the PlayStation Vita is the PSP's successor.
And although some things will be different, Sony is utilizing the same philosophy this time around: get software on the shelves ASAP.
In speaking to Edge , SCEE boss Jim Ryan reiterated Sony's primary focus with their new handheld. Said Ryan:
"To the extent that PSP targeted the core gamer who was after a good gaming experience, the philosophy is basically the same. But I think the nature of [Vita] allows us to provide a differentiated gaming experience in a manner that the design of PSP simply did not allow.
The core principle is to provide the best portable gaming experience possible. It's as simple as that."
The interesting part is that Ryan says Sony isn't sure of where the Vita will "end up." They consider the unit to be a "true digital device" but its path remains uncertain, likely due to constantly shifting market trends. We just know we want to try it.
