For those OOTL, Digsite was/is a team of volunteers from the Halo modding community who were given special access to official dev repositories by Microsoft and Halo Studios for Halo CE, 2, 3, and Reach. They have made quite a few releases since forming a little over a year ago including the full recreation of the Halo 2 E3 2004 demo, cut Halo Reach vehicles added to forge, and tons of cut CE content being re-added, all as mods on PC.
Sorry I guess I read in-between some lines. First post says ‘like a full time job’ and then the comment by OP says ‘E3 was more successful than Microsoft expected and they wanted another release on that level’ . I inferred that ‘E3 release’ boosted numbers and made somebody at Microsoft happy and they wanted another one asap and was probably not happy with the progress they made on a new release.
