I am not a day 1, but a first week in and am still in. I would be curious if 40% of people canceling is abnormal for a product that is 1 year in advance. Knowing human nature we buy when we can get it now. I know many people have buyers remorse and would be curious if they had the MMr in the back room last year and they were selling them for 8K how many people would have bought and then got home and said (crap what did I do).
40% seems high but for a purchase made a year ago maybe not.
