The franchise development director of Halo believes that the iconic game series can continue to be defining game for Xbox beyond the current console.
The Halo series is intrinsically linked with the rise and rise of the Xbox, with the first of the games becoming an iconic title for the original Xbox, the second becoming a massive illustration of why online gaming was central to the console and the glittering launch of the third illustrating just how huge it's successor - the Xbox 360 - had become.
Speaking to TechRadar at a preview event for the game, Frank O'Connor explained that he believed Halo 4 built on that legacy, and that the franchise would continue beyond the current generation.
Mario has been pivotal beyond the NES and SNES and N64 and...you get the idea.
People buy Microsoft consoles just for Halo, so obviously it'll be a big part of the Xbox 720 and even beyond that.
