I think it's FoxSports that is going to do the coverage, the last time round the coverage was CRAP, so don't expect too much, most Argentines don't even realise the Winter olympics are coming (I'm from Vancouver, so I've been bombarded about it for what, 5 years now or more?)
If you watch, keep an eye out for Kristina Groves in speed Skating -- she's my cousin and she's had a fantastic year so far (she's been No. One in a number of her distances all year) -- so she should be bringing home some Gold...
You're other hope for watching is via the net, you'll need to disguise your IP and a lot of sites have caught on to that so you'll have to be a bit more savvy than usual to get around it...
