Codenamed 'Durango' by Microsoft, often called the '720' by press, we may not get much officially on the new system until E3. Rumors and leaks have been trickling out for weeks now on XBox's next console. Whether the new console will use Blu-Ray, whether some sort of DRM will effect used games, and more.
Vgleaks posted leaked screenshots of yesterday from the development kit that offer a hint of some of the rumored features of the new console.
It seems that the units will have Blu-Ray players, something most of us considered a necessity to compete with Sony's PS4 and offer larger games, but play from the disc is not supported. All games will be loaded onto the hardrive. The exact size of the hard drive for 'Durango' isn't yet known, but is expected to be big enough to hold several large games.
The new console will also have an "always on, always connected" to the internet feature. Whether this will be used as a form of DRM is unknown, but could be used for background updates similar to what we saw with the PS4.
With entire games being installed on the hard drive and always-on connection it seems like they would need something to prevent players from simply installing the game and then selling off the disc once installed. This is where the belief that some sort of DRM, product code type feature, will be necessary for games.
