I disagree, name is not just a name. Its part of the identity. If the name is 6se i know for a fact that next year is going to be big because next year will be the iphone 7.I too don't care what they call it. Whatever it will be it, will be, who cares. It's not important, what is important is what it looks like, what it has inside and what it will do for me personally.
However, if the name is iphone 7, theres no proof next yr is called iphone 8 with all those high tech improvement, like a curved glass body.
