However, the way Apple collate those figures it is impossible to tell if people are buying the TouchBar models or the non-Touchbar models. There seems to be strong demand still for the "2015" model for example. I personally think the TouchBar is not the success they are making it out to be in terms of sales. We could argue that back and forth, but ultimately the only real sign we will get of this is what they do next. If the next version has no TouchBar we can conlcude it was not as successful as they wanted. If there are like 4 TouchBars on the next MBP I'll be forced to concede the point

(My own suspicion is that the will minimise or remove the TouchBar in its current form, replacign function keys, in favour of a pencil responsive Trackpad instead - with maybe a mini touchbar underneath the keyboard to either side).
Ming-Chi Kuo used to be reliable I agree, but in the last 12-18months he has not been so reliable. Didn't he predict a 32GB MBP in 2017 for example ?
