We probably won't get numbers from Apple but maybe some of the analysts may come up with whether the upgrade program is working. I certainly was not going to upgrade until I discovered I was in the new every year plan for the same payment. I have a similar program with adobe for my video editing software and I discovered I like it, when compared to paying the price for competitive at 20% more cost and then getting new features only once every 3 years. Adobe is constantly adding features for the same monthly payment. It's like renting a house where the landlord keeps adding additions and features, like new appliances all the time and never raising the rent. Sometimes, it's better to rent than own but not often. Technology is becoming that way since improvements happen so fast and costly. Owning is better when it doesn't improve much over the years, like furniture and clothing.
