With HD DVD out of the picture, Sony's challenge for Blu-ray is still threefold: competition against standard DVDs, people's wallets and limited selection. The vast majority of optical media in use today for movies is DVD. In both home entertainment centers and PCs, it is the ubiquitous format. The library of movies available on DVD is vast, and a DVD player can be had for dirt cheap. That said, Sony has starry eyes for its beloved DVD successor and thinks that Blu-ray will become huge this year.

In fact, Sony's expectations are for Blu-ray to take a massive 50% of the global market, or more than double the current amount of deployed units today. The Japanese giant claims they'll have this done before the end of this year, which is quite the lofty goal. Will they be able to do it?
