I'm in Canada, so I have my doubts it would be available right away. I would take the same approach Loss would though.
I've only skimmed this thread at most, are they actually going to even do it here? Seems like Sportsnet 360 is pushing themselves as the one-stop source for WWE in this country right now, and they'd have an absolutely massive fucking gap in their programming if it all goes to a WWE Network. It would be almost as bad as Gol TV post losing La Liga. :-)
I'd point out that Sportsnet also broadcasts the NFL Thursday Night game, despite NFL Network being available here as well as a specialty channel. There's a chance Raw at the very least could remain a Sportsnet property and they might not lose it all.
