Blu-ray is going to win this fight. Wal-Mart and Best Buy control a huge market share of the DVD purchasing industry, and Netflix and Blockbuster dominate rentals. All four back Blu-ray. The recent press that Blu-ray is getting (intentional, surely, as all of these companies want to get more people into the store) will raise recognition of Blu-ray discs, and Best Buy has said it will showcase Blu-ray, offering center store placement and sales to promote it. This means more people will be buying Blu-ray equipment in the near future.
