It's no secret that the console-gaming business hasn't exactly been setting the world on fire of late.

Today's announcement of the PS4 -- Sony's next-generation console -- comes after the longest period between product introductions in the history of the videogame industry. It's the struggling Japanese giant's latest, best hope to recapture some of the magic that vaulted it to the top when the original Playstation launched in 1994. But is it too late to matter?
