Yes. You are still wrong. On facts and logic.
Firstly that only applies to the US, it is certainly not anywhere near that here in Ireland. Common error on this Americanocentric forum.
Secondly even if you claim were true worldwide it would not be a good argument. Because you don't know if a cheaper model this year would sell better. Neither do I, however there are suggestions that it would because the iPad mini is outselling the iPad 4, and the iPad 2 did not outsell the iPad 3.
In fact you would expect lower priced models to outsell higher priced models in normal markets, and the fact that the old iPhone 4 isn't outselling the iPhone 5 is indicative that the strategy isn't working.
