BD is still a very small percentage of the DVD market.
At the moment. The driving force will be the major retailers: Best Buy, Wal-Mart, etc. WalMart is clearly moving toward BD based on shelf space, product placement, and pricing policy. The $10 BDs are getting prime shelf space while the $7.50 SDs are thrown in an aisle bin.

I've read a bit about the declining SD marketplace (to which I attribute too many reissues of the same titles...folks being frustrated about not getting the best possible quality the first time, etc.) as well as the sluggish acceptance rate of Blu-ray.
The BD format seems to be doing gangbusters in other countries, especially Australia where it seems to have outpaced SD discs in the past year.
The U.S. has GOT to make the shift to the new broadcasting format...and it needs to happen NOW, as scheduled. I recently read, however, that Obama has lent his support to a movement that would -- AGAIN -- delay the start of the new standards. I hope that doesn't happen because we'll never be readier than we are now.
Once folks find themselves between the rock and the hard place, they'll do what they need to do to get the proper converter signals into their sets.
