Apple is likely to make changes to the storage options for iPhone 7. The 64GB version, which has been the most popular option in previous generations, may be discontinued and replaced by the 128GB version, though this decision has yet to be finalized. On the other hand, Apple is certain to raise the maximum storage option to 256GB so that iPhone 7 will have the highest NAND Flash density of the entire series.
Thoughts, I think it's a wise move if it's true.
