Will ten million iPhone Duos be sold???

‌From my perspective as someone who has only used Galaxy my entire life, the Duo is a device I'd like to try once, but I wouldn't be able to buy it at that price.
However, people who have only used iPhones will likely switch in large numbers regardless of the price, right???
The Fold series sells in the 3 to 4 million range, so I'm curious to see how many Duos will be sold.
