Update from Superbike Planet:
"Update: beIN Sport USA, Al Jazeera's American sports channel, will take over broadcasting WSBK in the USA.
On the face of it, this is good news for those who feared the series would have no presence in the US. However, the beIN network does not have the reach that Speed did. Comcast, DirecTV and Dish Network seem to carry beIN Sport at this time.
Currently, there is no listing at all for WSBK on the beIN Sport schedule and the series kicks off this weekend. Additionally, there is no confirmation with WSBK that beIN Sport will televise the races in the US.
Suggestions that WSBK will be a streamed on-line in the USA seem muddled by the wording on the beIn Sport web site which states However, streaming will ONLY be available through an authentication system that verifies you are a customer of a cable TV, telco or satellite provider that carries beIN SPORT. In other words if you can see the race on your television then it will stream. "
Checked my Comcast listing and they do have BeIN, so fingers crossed...
