I have an answer as to why xfinity is not showing iron man 3. it is the same reason they did not offer oz the great and powerful. both movies are disney blockbusters and disney thinks that they will not be able to sell the dvds on these blockbuster movies if people can get them on demand the day of release. however, i have absolutely no explanation as to why comcast xfinity is promoting them as being available on their release dates but then not having them available. this is pure false advertising. welcome to consumer exploitation both by disney and xfinity. shame on them.
