Ok I was totally wrong. As outlined I won't reveal source if wrong since timeline was not part of the message. I took a chance that it was relating to iPhone X. Not trolling. So maybe next time. Maybe a larger iDevice.
Impressive phone and very clever strategy to have TID option also the cheaper option in the iP8, so people can't really complain they now have the phone they love with all the new hardware benefits under the hood. This avoided a misplacement-gate of TID.
I have no idea if the competition will ever catch up with the A-Chips.
Also does this mean the next and maybe last TID iPhone will be the 9.... iPX is the start and opening act of the new generation of phones and the next after that model it's Xs - brilliant if true.
