Sony's PlayStation 4 presentation might have been missing the obvious candidate -- a PlayStation 4 itself -- but made up for it with a selection of clips from new titles, tech demos, and franchise continuations.
While a Playstation 4 console was absent from its own debutant ball, a new motion and touch-sensitive PS4 controller were shown off, both designed to make gaming more intuitive in an age when touch and motion are becoming increasingly important.
And while the PlayStation 4, like the current PlayStation 3 and Xbox 360, is being touted as a do-everything entertainment hub, a particular emphasis was placed on its games -- or, in Sony's parlance, on "play."
Clips from a clutch of titles make up the PlayStation 4's round-up trailer.
Parisian developer Quantic Dream unveiled its new animation engine for PlayStation 4 development, and veteran game developer and PS4 design lead Mark Cerny showed "Knack," a game about a shape-changing robot.
Esteemed game designer Jonathan Blow revealed that his new project, intriguing island-based puzzler The Witness, would be exclusive to the PlayStation 4 for a limited time.
Sony developer Sucker Punch was one of a handful of teams that had not produced a PlayStation 3 game for a number of years, so the announcement of superpowered urban escapade InFamous: Second Son was in line with expectations, as was that of Guerilla Games' sci-fi shooter Killzone: Shadow Fall.
Sony's British racing specialist Evolution Studios is set for a departure from its MotorStorm offroading franchise with the team-based racing of DriveClub -- note that a Gran Turismo 6 was not presented -- and several third-party studios were also represented.
A red, laval knight and giant, blue-hued ice creature featured in a demonstration for Epic Games' Unreal Engine 4, a game creation suite aimed at developers; Havok's engine showed innumerable blue shards falling upon an ancient city; warriors and fantastical creatures faced off in Capcom's Deep Down, which bears much in common with 2012 surprise Dragon's Dogma, and the hugely anticipated Destiny, from Halo creator Bungie, made only its second public appearance.
