Blu Ray vs HD Battle

When will this useless war end? I have invested in a Playstation 3, so by default I guess I am in the Blu Ray camp. Wow does Planet Earth look great in Blu Ray, it sure is a treat. My best guess is that both formats will stay strong for another year or two. Both have too much invested in their respective formats to give up. Warner Brothers recently has said they will only produce movies in the Blu Ray format. Does that signal the death of HD? Na, they will pour some more money into the battle. Perhaps online downloading of movies will kill both formats in the end. I will hold off on building my Blu Ray collection for now. Thoughts?
