The vita development has taken a significant step forward and has now performed at 60fps for an entire half of a CPU vs CPU match without dropping a frame. While there are still changes to be made, this is a significant step forward in the Vita release development.
As this has now been proven to be possible for an entire half, a full match should be possible with no frame drops.
How this performs with a human player or netplay have yet to be tested.
Cross Play with PS4 still has to be investigated too as changes to the Vita release may hinder cross Play compatibility.
