According to Home Media Research, Blu-ray outsold HD DVD 2-to-1 in the US during the first half of '07. If you want the big numbers, it's 1.6 million Blu-ray units compared to 795,000 HD DVD units. If those numbers are too big, just take a look at the recent release of 300, which sold 190,000 units on Blu-ray and 97,000 on HD DVD.
Perhaps these two formats can seek peaceful coexistence, but as things stand right now, Blockbuster has gone Blu-ray and so have some retailers. We really don't care who wins the movie format war, but we'd prefer people spending their money on a couple extra games instead of possibly throwing their money away on a console attachment for a
dying not-selling-as-well format.
