An easier to develop one in comparison with Playstation 3's
Another rumor is circulating around the Internet indicating that the new PS4 will have Open GL support.
Playstation 3 uses LibGCM library which is hard to use when developing for the console.
A recent rumor from an anonymous font of TheSixthAxis claims that the future Playstation 4/Orbis will feature the well known OpenGL library, much easier to deal with for the programmers.
