I would have grave doubts except for the fact that is backed by massive ME oil money. They seem to be reaching deals with everyone to get their network in front of people, apparently giving rights holders 2x the money they are used to seeing, and the Comcasts of the world are getting their fat share as well. They should be fine.
The Al Jazeera brand will hurt them somewhat in the US, because...well you know people are pinheads about certain stuff these days. They should be called the "FUCKIN HELL YES AMERICA!!!" network here, or maybe the "TITTIES AND BEER" channel, then they can show soccer or whatever they want. Know your audience.
