Halo franchise up to 50M sold worldwide, next entry in the works
In the last month or so the Halo franchise shot past the 50 million mark for games sold worldwide, the figure being 46 million going into the launch of Halo 4 by 343 Industries. Microsoft revealed the new milestone to us via a recent press release.

The new figure would suggest sales of around 4 million for Master Chief's latest adventure, but it's those pesky other Halo games that are complicating the issue. We do know the Xbox 360 shooter made $220 million on its first day at retail – not bad when you consider the multi-platform Black Ops 2 did $500 million in the same time, with more expensive special editions.

343's Development Director, Frank O'Connor, revealed this week that the next major Halo game was already in the works before Halo 4 launched. Speaking to CVG, O'Connor said, "I can't say more than that, but work on the game started actually before we launched Halo 4 and continues apace as we cycle staff through the team's vacation breaks. We're excited about the next game."
