You may be jonesing for a follow-up to the PlayStation Vita, but Sony isn't so sure that it's a wise idea. The company's Shuhei Yoshida told those at a recent developer session that the "climate is not healthy" for a Vita sequel. Simply put, he believes that smartphones have dampened enthusiasm for gaming handhelds. Why get a dedicated device and buy games when you can play free games on the device you already have? He hopes that the culture of portable gaming will live on, but he doesn't currently see Sony fostering that culture with new hardware.
