I've been a long time lingerer, and I have posted here a few times before, but this has been bugging me so I felt the need to login and post.
Before we look at what I expect for the future lineup, let's take a look at the current lineup. Prices are off contract (aka, actual) prices.
5C 8gb ~500
5S 16gb- 650
5S 32gb- 750
5S 64gb- 850
This is all just my opinion/educated guess, but I have a feeling they will only bring out one or two...
