Could this be the first glimpse of the next Halo title which is in the works at 343 industries? While it's exciting to think that it could be, one thing is definitely missing, and it's Tom Morello's signature all over the image. And of course the fact that the radar in the bottom left looks a little suspect. As well as the deviation from the traditional font's, but hey, it could be a very rough build.
But, I highly doubt that, even if it is a very rough build, this is an actual in-game screen. First of all, 343-industries already told us the wait will probably very long, and the radar just gives too much away.
