Let's look at this another way. If you are one of the power users with 100s of movies and TV shows in the queue, then why should it matter if this particular title is taking longer to show up? Is it more important than the other material by virtue of being more recent? If it matters to a person that they see the new releases more quickly, then they should use the theater or brick and mortar rental options.
The power users are getting a great value for their money, and it's not a feasible business model for Netflix to plan extensively for those exceptional cases where power users care about getting the newest release right away.
