These numbers look good, but the DVD version will probably outsell the Blu-Ray one by a larger margin for months to come.
First day buyers = enthusiastic movie fans = people who tend to have Blu-Ray (i.e. the same reason why core games have less legs than casual ones)
Definitely good news for Blu-Ray, but let's not pretend it has 30% of the market share even for new movies.
