The Only real phone that has the most mystery is the 6.1 LCD iPhone and perhaps an unreleased version two of the SE. But otherwise the 5.8 physically won’t have a lot of external changes, and even the price may or may not reflect a drop. But even if a 6.5 iPhone X releases, its going to be a larger version of the 5.8 with some enhanced features. Consumers may not make their decision until after they see the phone, but the reality is, they know what size they probably will prefer before it launches based on what’s comfortable to them and their budget or when they are eligible for an upgrade.
For example, I prefer larger iPhones because the bigger battery and larger display, which in all likeliness, I will choose the 6.5 iPhone X, because that will be more in tune to what I have been looking for, regardless of the rumors or not.
