It will be a crowd of fat ladies yodeling once a major release comes out - and is ONLY available on high definition. Might be quite a long time before we see that, maybe only long after the war is settled.
Unless $ony decides to use one of it's companies to give a major boost to another of it's companies. It might not even involve a big loss on their part. Just release it on Blu-ray only, it helps drive sales of players, then more people will buy the movie. And then, after a year, say, release a standard DVD version. You've delayed profits, but for the mega company as a whole, increased them and solidified the format. This would have to be done carefully, and not too soon. You'd have to have some players out at lower prices.
