Bungie got really huge with
Halo. It did alright with
Marathon, but Halo was the series that turned them into one of the big boys. On March 31, they are going to turn over all their Halo services to 343 Industries, thus cutting the cord on the franchise they started.
343 Industries is working on
Halo 4 and they'll be taking over, along with Microsoft, all the services that involve Halo. Now, all the old data will stay on Bugie.Net's servers as long as possible. But starting April 1, 343 Industries and Microsoft will be the good to companies for support in user generated content.
