I'm really counting on it being the iPhone 8, not Edition or Pro. Edition reminds me of that stupid Watch Edition that was crazy money and more luxury. This needs to be the main iPhone everyone will get this year, not some novelty device. I know it's an S year, but history can be rewritten and easily release the 7S and 7S Plus, plus a phone named the 8. I'll be disappointed if it's called Edition or Anniversary or Pro. Just call it the 8. That's what we've been calling it until these recent rumors. I'm going to refer to it as the 8 regardless what they call it, cause I'm a rebel. But yeah, I'm betting 8.
The Apple Watch still has an Edition it's the Ceramic Edition and it costs £1,299 it looks really good but Apple will more than likely add a new Apple Watch Edition at the event alongside the new Apple Watches. The Edition makes sense due to it's OLED screen, glass back and so on, also the price is going to be higher than the 7s and 7s Plus (it's rumoured to start at around $999).
