YES! I definately want that too. I mean, c'mon its just another disk in the package! Plus then it allows them to sell both the BluRay and regular DVD using ONE SKU/UPC instead of having multiples or confusing customers plus I would actually almost be more tempted to look for a cheap bluray player if I already had a nice selection of BluRay disks around y'know?
They will sell more blue ray disks. For those that want to future proof themselves.
