My best guess, the color model iPhone will not have the finger print reader, the camera will be 8mp, and carry the same chip as the 5.
16gb off contract 349.00
16gb with contract 79.00
5s
Finger print reader, 12mp camera 120FPS video feature, higher storage, storage will HAVE to go up with 120FPS, 16gb would be silly small.
32gb 649/199
64gb 749/299
128gb 849/399...I think 128 will sell well with the new camera and 120FPS
iPhone 4 still the free phone, 4s and 5 discontinued, the color will be close to what the 5 was. And for just 79.00 why go for the free one? Apple will make the 79.00 iPhone so compelling most will not go for a free phone and choose to pay the 79.
Taking previous years cost to carriers, Apple could make $200 on the S and 125 on the color ballpark. I assume they want to keep the profit between the two phones as close as they can, so no matter what you choose $$$$
Can they pull it off? hard to say, they will lose some upgrades from the 4 or 4s moving to the color instead of the 5s, and lose some from new buyers going to the color. But they are banking on a LOT of new buyers and the past free phone contracts who got the 4, to just go to the color.
I think it will work for the most part, But I don't think this will translate into a lot of sales in other countries, 349 off contract is a lot cheaper, BUT still pretty high compared to android.
