I think this will be a bad move on blockbusters part. Unless they carry both versions I have strong doubts on the effectiveness and popularity of the Blu-Ray disks especially after that stuff sony tried to pull with their CD scandal. DVD is how it's going to be. I forsee a drop in blockbuster market shares from this. Unless you use a sony influenced DVD player Blue RAy disks won't work on it. We shall see, all we can do at this time is speculate and point and laugh if they fall on their faces.
