It seems to me the reasonable strategy would be to leave the ending of Halo2 at least decently open, so Bungie can go on with another sequel if Halo2 sells well - and I don't think anyone believes that it won't, unless it's a disaster. If things go as planned, with such a cash cow as Halo has turned out to be, it would be crazy not to take it further.
Other than that, with the Halo-project having been around for so long, with Halo2 taking its own sweet time to develop as well, and with three books published, I'd be surprised if the people behind Halo don't already have a pretty clear idea of where to take the story next.
