They could show the OHL games in HD but they choose not to do that..
They did their CHL game of the week in HD a couple of years ago, but since then, they seem to have decided the only HD worth doing is baseball. We're not going to see NHL games in HD on Sportsnet as their rights are assigned to their regional stations and their HD license is national. At some point, though, they'll have to come to grips with converting their regional entities to HD as well; if Fox Sports can do it in America, why can't Sportsnet do it here?
Meanwhile, TSN has stepped up bigtime, especially in hockey. Their HD broadcasts of the World Juniors from Sweden were outstanding and last Wednesday we even got a hockey quadruple header in HD (two WJC semifinals and two NHL games).
I've got to agree with the OP on the PPV games though; as long as they're still in crappy SD I won't be buying.
The fact is that only about 5% of Canadians have HD and subscribe to HD programming. If you were in business, would you invest your capital and programming budgets to service 5% of your audience?
Yeah, but I think that is changing very quickly. In the past month alone, the number of HD-enabled viewers in my circle of friends, acquaintances and colleages has increased six-fold. Virtually every tv being sold now is HD-capable and consumers are eager to fill those newly-acquired widescreens with sharp, vivid programming. Any broadcaster that is looking at that growing bubble and not factoring HD upgrades into their equipment acquisition/update cycles is shortsighted and doomed to the viewing backwater (hello CanWest Global?). This includes the NHL teams with PPV, as more and more bars, the bread and butter for those broadcasts, become HD capable.
