A new version of the PlayStation 4 dev kit is currently being distributed to developers with the final version expected next year, according to a new report.
Anonymous sources have reportedly told VG247 that new versions of the Orbis kit are winging their way to developers, replete with Blu-ray support and housed in the humble cases of normal PCs.
This is apparently the second iteration of the dev kit; the first, which appeared earlier this year, was in essence just a graphics card, while this version is now a "modified PC". The report asserts that the next update will come in January, when it'll be close to final specifications, with the ultimate version landing with devs next summer.
The shipping of the Orbis kit apparently follows a series of meetings held by Sony in the US this week, where the company explained what the machine was designed to do and how to get the most out of it. Interestingly, at these meetings it's been claimed that Sony didn't refer to the machine as "the PlayStation 4" at all, instead opting to use the "Orbis" title at all times.
The dev kits are apparently based on the AMD’s A10 APU series and come with either 8GB or 16GB of RAM, as well as the Blu-ray drive already mentioned and a 256GB hard drive as standard. This is to ensure that the console will be able to run 1080p60 games in 3D.
The Orbis kits have both Wi-Fi and Ethernet connectivity, as well as HDMI out slots; so pretty much exactly what you'd expect to find on your current PlayStation 3. However, the big reported difference comes with the UI, which has been designed to be more fluid and allow extensive navigation anywhere on the system simply by pressing the PS button mid-game. This was demoed to the assembled masses by purchasing DLC from the PS Store without quitting the game.
