This change sucks, mostly because of how Disney has handled the transition. After five years or so of iTunes digital copies being the norm for them, they changed course with no notice to customers on the packaging, press or anywhere else. I pre-ordered all five thinking, "great, digital copies!" only to find that none have them in a format I can use. They had it right with OZ - a disc-free system which offered a broad range of compatibility. Since there's no real reason why they CAN'T offer iTunes along with the other services, the exclusion seems petty and anti-customer.
Truth be told, though, these five recent releases that do not have the iTunes digital copies are all titles that, in all likelihood,would not have had digital copies at all, just a few months ago. However, they have now added "digital copy" into the value equation and, when that portion of the product is useless to me now, that makes the expense harder to justify. This change has pushed me from being a blind Disney pre-orderer to, now, a "wait and see" customer with their titles. Owning everything on DVD to begin with, I can't really justify the expense of "upgrades" if I'm not going to get my full value use of the product.
