I saw a news report several months ago where the WWE was purchasing HD equipment. Since they are just now purchasing the equipment, I doubt they will have it ready by next month.
I asked a friend there and it appears the answer is no. While they have started upgrading their equipment to HD it all has not ben updated yet to make it possible.
Actually the WWE will be renting their equipment from what I've heard. As for where they will broadcast it that I am interested in myself. They have a tv deal with Spike and are working on jumping over to USA Network, neither networks are broadcasted in HD. As for the PPV's would they air those on HD PPV?
