SketchFactor pointed us through Truth & Reconciliation to a page at iGames where they are summarizing the Halo for Windows Worldwide Final results.

Currently it looks like Jonathan "Beast" Finglass of the UK is doing particularly well. It's not entirely clear to me if the tournament is over just yet; all the grids on that page are full, and the previous grids were named quarterfinals and semifinals, but there's no announcement of any winner there yet, but neither are there schedules up for more rounds, at least not yet.

Sketch promises a full writeup later in the week.
