I really do not think they will. The Vita and PSP seems to not have done very well in all accounts. I feel like they will stick to the main consoles completely after the seemingly bad sales of PS TV as well.
Instead I feel that they will focus on making PlayStation now compatible with as much hardware as possible (maybe including tablets and phones on Android, iOS?) instead to earn money in the handheld market that way.
