At GDC 2013 at the end of April, a room full of would-be PS4 developers and press got some new details about the hardware, controller, online and social functions of the forthcoming PlayStation 4.
Senior Staff Developer Support Engineer Chris Norden unveiled the news under an overarching theme of a "frictionless and seamless" gaming experience.
We've known that the PS4 will track both the controller in a gamer's hand, as well as their face, since the console's launch in Feb. But during his GDC talk Norden revealed some interesting ways that this technology will be implemented in games.
For example, the old multiplayer standby of split screen, divvying up television real estate when two or more players go at it, will be aided by this tracking tech. If a gamer gets up and moves right or left, his section of the screen will automatically be swapped.
The PS4 release date is "Holiday 2013" for the USA. That's the only official detail Sony revealed at the launch in February and it's unclear which other territories it applies to, if any.
In an interview in May with our buddies at CVG, a source inside Sony said that the company is pulling out all the stops to launch worldwide in 2013 and ensure that the PS4 is not trumped by the new Xbox.
Officially, Sony has said it wants the PS4 release date in Europe to be as soon as possible but makes no promises on whether the UK and other European countries will get a release date in time for Christmas this year or whether it'll be an uncomfortable wait until sometime in 2014.
Stock issues might be the reason for this, and that's exactly what happened back in 2006/2007 when the PS3 launched. It went on sale in the US and Japan in time for Christmas and Europe and the rest of the world had to wait for March the next year.
Zavvi has actually listed a UK PS4 release date of 31st December which seems extremely unlikely - launching a few days after Christmas? Surely that's retail suicide.
Until Sony gives more details then, it's all just speculation. Even the retailers don't seem to know when the PS4 will release - so maybe Sony doesn't either. It could depend on how quickly they can get manufacture going on retail models, what yield rates are and the capacity of the factories.
Until we know more, we'll quietly pray to the gods of silicon that the PS4 release date will be Christmas 2013 worldwide. Or better yet, tomorrow!
