Overpduction of the 5C? It was the third best selling phone in the world last year. iPhone 5S being number one if course
The 5.5" is real and is going to happen. They will have to do something to compete with the G3. I recently bought one and hands down it is the best electronic device I have ever owned. The screen alone blows everything else out of the water.
In your mind you may think it is too big, but in reality it works. People are hungry for bigger screens, Apple for once will have to do something to fill a need, rather than sit back and dictate what the market will bear. I think they may have learned their lesson with the overproduction of the 5C and the underproduction of the 5S.
The Model T days of Apple are over.
