Newsbrief: Popular game development environment Unity is coming to all of Sony's PlayStation platforms. Unity already supports PlayStation 3, but new versions currently in the early stages of development will support the PlayStation 4, the Vita, PlayStation Mobile, and Sony's upcoming cloud gaming service as well. While Unity will be present at GDC next week, it says that work on these platforms is too early to show off, though a release is expected this year. More on the Unity Blog.
