There were rumours a few years ago about Apple doing away with the numbers altogether (which surely they'll have to do eventually? iPhone 14 anyone? Meh, who knows). I think it makes too much sense financially for them to remove the S line though.
Everything that I've read so far on different forums seems like speculation. I guess time will tell..
The name is really tough for this one, since the S models usually are just refinments on the "main" models. My guess would be iPhone 8 or just iPhone, but who knows. I am not sure if the common consumer even cares about the name, to them it might just be "the new iPhone" and maybe that's all that matters
Everyone keeps talking about the iPhone 8 in 2017, is apple skipping the 7s or something
I hope they drop numbers all together. Redefine the iPhone.
