Sure, you're absolutely right it was rumored for ages, but the OP's point (last year) was that the wording in the iPhone 7 design video hinted strongly that a completely new design (not an evolution of the existing design) would come out the following year, and it did. (He never said that a model based on the existing design wouldn't be released alongside, so he wasn't wrong there either!)
iPhone 7 design video: "We have created a product that is the most deliberate
evolution of our original founding design"
also iPhone 7 design video: "iPhone 7 is the most singular,
most evolved representation of
this design"
I mean seriously, it's almost screaming at us "but hey guys, we have this
other design over here" which is why I was surprised that so many people made fun of the OPs prediction, and thought the post deserved some recognition.
The
iPhone X design video pretty much confirms it:
"For more than a decade our intention has been to create an iPhone that is all display... This is iPhone X"
Jony Ive was clearly bursting to say this at the end of the iPhone 7 design video but had to keep his trap shut for a further year.
