I also know that Bungie wasn't always Bungie. They used to have some other name, but right before the 7th day 7th column thing they weren't Bungie. And that the reasoning behind "selling" Halo rights to 343 was so that they could make Halo 4, but also be able to make games like Reach, Wars, and ODST to push back the date of it so they could test some of their ideas to put into the game. They have been working on Halo 4 since ODST came out.
