If you look at the pie chart for Blu-Ray corporate support  on Wikipedia right this second, you’ll see that a battle is currently being waged with Blu-Ray currently leading in terms of exclusive contracts. Well, if you have been keeping up with the news, it was reported recently that Warner has gone exclusively to Blu-Ray  and that Paramount has a clause that lets it switch to Blu-Ray  if Warner went to Blu-Ray. Warner switched and it’s likely that Paramount will join since one format certainly benefits everyone except the folks backing the losing format. Sony may have lost the Betamax vs. VHS battle but they got it right this time.
So, want a quick primer on what the differences are? Engadget has a great comparison  but the basic gist is that Blu-ray discs will be more expensive because they carry more.
I hope all you folks who were early adopters and got yourself an HD-DVD player can return it in time. 🙂 [or I could be wrong, HD-DVD could stage a heroic comeback and this post will go down in the annals along with Chicago Daily Tribune’s erroneous headline of Dewey beating Truman ]
