Ever since Bungie and Microsoft parted ways, Microsoft have been gearing up to produce more Halo games internally. Could those efforts now have been given a name?
Superannuation points us towards a trademark Microsoft have filed for use with ""computer programs, namely, game software for use on computers and video". It's called "343 Industries". So far, so boring.
But then consider what "343" means. In Halo, it's the name given to 343 Guilty Spark, that floaty little machine whose sole purpose is to hover around, pissing you off. And 343 Guilty Spark is, as GameSpot point out, not only an annoying minor character. He's also revered as an oracle by the Covenant, and for all his small stature, remember, he spends most of his time trying to trigger the Halos and destroy the known universe.
Then consider that "343 Industries" sounds a lot more like a studio than a game and you're onto something. Microsoft would only respond to GameSpot with "We have nothing to announce at this time".
