The following stats are taken from the Nielson Videoscan ratings information in Home Media Magazine:
Data up to and including the week ending March 18th 2007:
SI, Blu-ray:HD-DVD
100:84.07
YTD, Blu-ray:HD-DVD
100:44.44
Based on comparisons of week to week sales ratios from the same source, we can estimate that for the week ending on March 18th 2007, the sales for Blu-Ray vs. HD DVD were roughly 100:23 respectively, or just shy of 4.5:1, which is also about the same as last week.
