As it happened: Sony didn't unveil the PlayStation 4 at PS4 event

New York: Sony's PlayStation 4 event ended without it showing off the device or even mentioning anything about PS4's price.

Underscoring the importance of a new PlayStation and the US market, Sony held its announcement event in New York rather than in Japan, as it had in the past. The event was at the Hammerstein Ballroom in midtown Manhattan.

Here's a running account of the PlayStation event, presented in chronological order. All times are EST. Presenters included Andrew House, president and group chief executive of Sony Computer Entertainment; Mark Cerny, lead architect for the PlayStation 4; and David Perry, co-founder of the Internet game company Gaikai, which Sony bought last year.

6 PM: The PlayStation event begins with a light and video show at the storied Hammerstein Ballroom in midtown Manhattan. In attendance are analysts and journalists representing news organizations around the world.

6:10 PM: Just before announcing the PlayStation 4, House refers to "a moment of truth and a bold step forward for PlayStation and the company." He says Sony is looking to offer powerful opportunities to connect and play, including on mobile through a companion PlayStation Vita released last year.

6:25 PM: Cerny appears in a plaid shirt and jeans as he touts the ease in which computer programmers will be able to write games for the new system. He says that with so many devices around, the value of having a powerful computer on a single chip has diminished. Instead, Sony is building the new PlayStation on top of a traditional PC architecture, and in doing so, game creators will have an easier time developing games.

6:30 PM: Cerny says the new PlayStation will have hardware compression so sharing video of game play will be easier. You can browse live game video of games your friends are playing.

Adopting Facebook's philosophy, Sony will transition to an online game network based on real names, even as people will also be able to keep their aliases.

6:40 PM: Perry talks about Gaikai's vision of letting people explore any game in the PlayStation store for free. The idea is gamers will then buy what they like.

He says PlayStation 4 will allow for virtual spectating. With one button, you can broadcast your game play so friends can "look over your shoulder virtually."

It will have a feature called remote play, in which you run the game on the PlayStation, which then sends the video to your handheld PlayStation Vita device over the Internet so you can play remotely.

6:45 PM: Like Nintendo and Microsoft, Sony is trying to position its device as an entertainment hub that can deliver movies, music and social networking as it tries to stay relevant in the age of smartphones and tablets.

The PlayStation online network will have access to Sony's video and music services, as well as Netflix, Hulu and Amazon - as long as you have subscriptions to those services. You'll also be able to access Facebook.

6:50 PM: The event continues with demonstration of games that can be played on the new PlayStation.

7 PM: Among the offerings planned: "Drive Club." An executive from Evolution Studios says it's been a concept for a decade, but made possible with the new machine. The game will be about driving the best cars in the world in the best locations in the world, using 3-D models of engines built by the development team.

7:15 PM: Another game showcased was "The Witness." It's a puzzle game that explores an abandoned island. It will be developed exclusively for the PlayStation 4.

7:25 PM: Beyond games, Sony is touting the PlayStation 4's fast graphical capabilities. You'd be able to create animation in 3-D using a Move motion controller - all in real time.

7:30 PM: It's 9:30 AM Thursday in Tokyo, and the event is being streamed live at Sony's website.

Yoshinori Ono from Japanese game maker Capcom addresses the audience in Japanese, with a translator offering the remarks in English.

7:40 PM: More than an hour and a half into the presentation, Sony has yet to show the PlayStation 4 machine. There's no word yet on price or release date, though availability isn't likely for several months.

7:50 PM: Sony continues to bring game developers on stage to talk about upcoming releases and plans for the PlayStation 4. Video from the various games is shown on the giant screen.

8:05 PM: The event wraps up without Sony showing off the device or saying anything about price or availability. The event focused on the new console's social and remote features and games that are being developed for it.

Sony says the "PS4 is coming Holiday 2013."
