Concept Art of a New Halo 4 Multiplayer Map?

This is what halouniverse said about this picture

"A few hours ago, it leaked online a fantastic artwork by Halo 4 representing a new Multiplayer/Spartan Ops map, which however do not yet know virtually nothing, except some possible detail due to its appearance. The map, of generous size, and that has some human structures, seems to fit the frenzied clashes Big Team Battle that Halo has always been accustomed. Furthermore, since there are no mountain ranges scattered in the middle of the arena game, you can expect the use of aircraft. I propose to follow the artwork, stay tuned for updates."
