I see over 100 views with no response, but a little bit of searching has come up with an answer.
Expressvu will be carrying WWE Royal Rumble in HD this year. It is listed on their site in the what's on in HD page under sports. This is probably going to be the first WWE event in HD, so this should be interesting to see. I haven't purchased a pay per view in a long time, but I will be getting this one.
I noticed that too in the magazine, but I would assume the magazine was printed well before WWE made any announcement that the Rumble would be HD. Bell's website says it is showing in HD this month. Click on High Definition, then click on the Rush Hour 3 beside playing this month in HD. This brings up a list of other HD events and the Rumble is listed under sports.
I'm not sure if StarChoice will be showing it in HD. It is not listing on the website. Bell has it listed under pay per view events now for $49.99 as well as a seperate listing for the Rumble in SD. If StarChoice hasn't shown a UFC event in HD yet, then chances are that they won't be showing the Rumble either.
