HD-DVD Vs. Blu-Ray battle heats up

A few weeks ago at E3, Sony announced that it was going to drop the price of its PS3 by $100. In response to the news, Microsoft said that it thought that the price of the Xbox 360 was “competitive.” That was then.
Today at Comic-Con, Microsoft decided that a price drop would be a good idea, just not on the system. The $20 price drop will be on the 360 HD-DVD drive, bringing the price down to $179. Along with the price cut, customers will be allowed to chose 5 free movies from a pre-selected list of 15, which they can then receive by the mail. Here is the list of the selected movies: Apollo 13, Blazing Saddles, Casablanca, Chronicles of Riddick, Constantine, Dukes of Hazzard, Four Brothers, Tomb Raider, Perfect Storm, Rundown, Seabiscuit, Sky Captain & the World of Tomorrow, U2: Rattle & Hum, U-571 and We Were Soldiers.
Additionally, to help promote HD-DVD as the next video entertainment medium, the movie 300 and the TV series Heroes which will be launched in upcoming weeks, will have exclusive content available on Xbox LIVEĀ® Marketplace.
On the other hand, Blockbuster has decided to stock Blu-Ray discs on its shelves rather than HD-DVD’s.
So the battle is still raging over which format will survive. This is Betamax Vs. VHS all over again.

What the hell is a Betamax?
