thanks for the quick answers guys. GLWIZ quality doesn't do it for me, and I checked fifa.com and found no trace of any sort of live-streaming section (I read the same blog post as you Pooya). I know betting sites like bet365 show them too, but they usually require you to sing up with a credit card [and I guess deposit some betting money too].
Anyway, hopefully someone will stream it on ustream or something.
