The PS4 hints at plenty of other possibilities. Local network play via the PS Vita has an enormous amount of potential. The PlayStation App and even the Playstation Camera may provide opportunities for developers to broaden the appeal of the PlayStation 4 beyond the hardcore audience it currently seems so intent on courting. Unlike the PlayStation 3, Sony's latest effort was built to evolve.
But the PlayStation 4's focus on gaming — and only gaming — is undermined by a distinct lack of compelling software. That failing is sure to improve — better games and more of them will appear on the PlayStation 4 — but right now, this is a game console without a game to recommend it. Early adopters of the PS4 this fall are buying potential energy. We're just waiting for a place to spend it.
