The entire third act of the plot is missing beacuse Bungie developers still had not finished it and they refused to delay release again and miss Xmas shopping season. Hence the abrupt ending. There is a lot of speculation as to it being in downloadable content or an expansion pack realeased on Feb 9th 2005. As you finish the game watch the credits roll. At end it says "Coming Feb 9th" or something like that.
The February 9th bit is a total rumor, and Bungie themselves shot that one down. However, I did read in the Official XBOX magazine that the third act was indeed intentionally omitted, but what happens with it is indeed a subject of much speculation.
Frankly, I think the most sensible way to go would be for Bungie to use it as a jump-start towards the next Halo installment on XBOX Next. Each bit of Halo in-game plot is a precious gem, in Bungie's perspective, and I can't see them "wasting" it on a D/L content. Bungie/Halo fanatics would go for it, but in the wake of the Halo 2 frenzy, I can see it getting lost in the noise.
However, I could very well see it as some part of the XBOX Next launch. Microsoft knows a Halo title would move hardware, and I bet they already have a plan for XBOX Next that includes a Halo title. Since Bungie runs a very, very tight ship, I bet they could keep something like this a secret for as long as possible.
We can only hope!
