Theory about iPhone 9
What if Apple would be releasing an iPhone 9 in the future with a homebutton again.
I know this is a weird suggestion but consider that they lately made a lot of different phones to satisfy the biggest groups of users.
They made the plus iPhones for people that wanted a bigger phone, they then again made the se that satisfied people that wanted a smaller screen but not mis out on the better hardwear. Now they also have the xr for people that want to pay less for a cheaper yet still good screen.
So to me it seems logical they will come up with the iPhone 9 in the future. Of course they started a whole new thing with the x line and wont call a phone with a homebutton something with an X. Also this would be a huge publicity stunt since nobody would expext it. And they can release an iPhone 11 as a matter of speaking to launch at the same time
