NBC are nationally televising 3 matches of the world cup in free HD. Starting with this one Sunday at 2pm (won't lie to you, likely to get ugly for the US but I'm watchin anyway)
The other two matches they will air are New Zealand vs Canada (an equal blowout) and the best of all the Final. If you are lucky enough to live in Canada, you can see those NBC matches plus a far greater selection on TSN.
Anyway, the whole tourney kicks off in 6 hours if anybody wants to watch Kiwi's vs Tongans.
