You still haven't answered one very simple question so that I know where you are coming from.... What do YOU consider a flop? 100,000? 500,000? 1,000,000? 5,000,000? 10,000,000? 100,000,000?
(And the 16 Pro not selling as well as last gen, again, does not make it a flop unless Apple have come out and said it will be a flop unless it sells more than last gen)
