It is inevitable that Apple will manufacture a new iPhone with a bigger screen within the next year. There is no doubt that the majority of users want a bigger screened iPhone but there is widespread opinions as to how big. I envision that the 5C will remain in the lineup in the coming years as an "iPhone Mini" that will retain the 4 inch screen and will keep getting upgraded for the users who prefer the 4 inch screen and those who want a cheaper iPhone. The new flagship model will have the larger screen. I don't see it having a screen larger than 5 inches even though the news have been mentioning up to 6 inches, I just don't see it. They could always make a 6 inch as a new product separate from the flagship iPhone model, but I really don't see it. So, what size do you want?
