While the vita is a nice piece of hardware with good games available... the sales numbers have been anything but good. Sony is not in a good financial position, and a loss leader is not what they need.
I hope things improve for them, but I don't think the odds are good.
Prediction, a new CEO at Sony cuts the system next year in favour of smart phone partnerships as a lower risk strategy. (hey I made a prediction) Not on the quality of the hardware, just the financial position of the company. It is the shareholders not the fans who get the ear of the CEO.
