GotFrag's coverage of the MLG 3v3 Arena Tournament in Orlando begins at 9am Eastern, 6am Pacific today. If you didn't tune in at all last month, I definitely recommend doing so this time around. Generally, I'm not a PvP fan, but this was very fun to watch last time. WoW's impact as an eSport isn't really something you can witness in-game (which is a shame) but for me, tournaments like this give it a whole new dynamic. The emphasis is placed more on the players and the choices they make, and a little less on rock-paper-scissors and endless countercomping. It's an all weekend event, so if you're only interested in watching the finals, that'll be tomorrow.
Like Amanda Dean and GotFrag themselves detailed the other day, there are a lot of teams to keep an eye on this time around. Frag Dominant took the win last month, and there are plenty of other teams you may recognize. SK-Gaming, MoB, Got Game East/West, Pandemic, Fnatic, plenty more. If you don't keep an eye on the PvP scene on a regular basis you might not recognize those names, but they put on a good show last time.
To view the live stream, you will probably be prompted to install a codec if you don't have it yet. All of us WoW players are a little paranoid these days (with good reason), so don't be afraid to run a background check on anything you're asked to download. I'm pretty positive there's nothing to worry about in this case, but better safe than sorry, eh?
