With 3D technology on the rise, it is no surprise that we are starting to see 3D effect technology in video games. We've seen it start to surface both on the PS3 and Xbox 360. Even the upcoming Nintendo Wii U is said to handle 3D technologies, though it won't be a major push for Nintendo. While current-gen 3D is a good start, it is likely that 3D won't really become important to gaming until the eight generation of consoles officially start.
So far we know little solid information about the Xbox 720, but a new job listing recently posted certainly suggests that 3D might play a fairly important role.
