According to Ross Rubin of NPD, “It has only been a couple of weeks since the Warner Bros. announcement [of exclusive support for Blu-ray], as well as Toshiba’s price promotions, Microsoft’s lowering the price on its HD DVD Xbox peripheral and the [Toshiba] HD DVD Super Bowl ad. So, the story continues to evolve. The two formats ended 2007 essentially in a dead heat. Until one camp decides to give up its format we are going to continue to see confusion at retail.”
Rather than talking about sales though, it might be more useful to think in terms of losses. While Sony's Blu-ray players and Toshiba's HD DVD models are in a virtual tie for units sold, when it comes to percentage of overall revenue from those players Sony has approximately a 2:1 advantage. Neither company is actually making money in the Hi-Def DVD player market, unless that situation changes soon it could become a question of who has the resources (and nerve) to continue supporting the cost of competing.
It seems unlikely that either will become profitable except as the lone HD disc option, and even then there's no guarantee. In other words we're just about back where we were before the Warner Bros. announcement at the beginning of the year.
