I haven't seen any credible rumors on 14". At least none credible enough to be mentioned by MacRumors. This is why I was asking where this rumor came from.
5G rumors? Yes. Mini-LED rumors? Yes.
Why is 14" the next logical step instead of refreshed 13"? The 16" chassis makes sense to house a power-hungry i9, discrete graphics, and good speakers. I don't see the same argument for 14".
Rumours don't have to be credible to be reported on here. The site originally started to just gather together all rumours about Apple stuff. There's also other places which have their own sources.
I've read a couple of rumours of a 14" screen over the last 12-18 months but I couldn't tell you where or when they were as there's so many rumours reported every week.
It would seem logical because they've managed to put a 16" screen in to the 15" body whilst only making it slightly larger. The 16" chassis seems to be almost the same size as the 15", so its not like they've had to make it larger to accommodate all the new gear. Some people thought the 16" would be a bigger machine alongside the 15" in order for it to be much more powerful but that's not happened.
I still don't see why people put so much stock in Kuo, he often gets stuff wrong and some of predictions are vague to the point of being not much use unless someone else chimes in with another rumour which will often put some context around it.
Apple
might take the same ideas to the 13", they might not. But I could see them doing it as it would keep the proportions the same if nothing else and they do like to do things like that. Will the new keyboard necessitate a slightly re-designed chassis in which case they might do the screen too?
