I don't expect an upgrade to the 4S. But I do expect them to keep the 4 in the line-up at 8GB, the 4S at 8GB or 16GB, and start the 5 at 16GB or maybe even start at 32GB and go as high as 128GB. Now that would be exciting. In addition, depending on storage and LTE chipsets, I expect the 5 could start $50 higher than the 4S prices.
