As a fan of the fighting game scene (and a player that belongs nowhere near it) it's not often that I forget to watch a major tournament on the Road to EVO. Thankfully I subscribe to LevelupLive on Twitch. LevelUpLive is currnetly broadcasting day one of SoCal Regionals and tuning in right now you can check out the pools for Super Street Fighter IV AE, but they will be running multiple streams all weekend and featuring multiple games such as Ultimate Marvel vs. Capcom 3, Super Smash Bros. Melee, BlazBlue: Chronophantasma, and more.
You can check out Shoryuken.com for more info on each of the streams as well as upcoming exhibition matches, and for those with amazing bandwidth capabilities you can check out all six streams at one. You may laugh at the thought of Smash Bros. at a major tournament, but to be honest it's one of my favorite "fighting games" to watch aside from Street Fighter and Marvel.
