Basically the ancient oracle at Delphi was more accurate than these "predictions" this whole year.
It might be one, it might be the other, one thing is for certain, something might actually happen.
In general, I don't know if I am allowed to talk about this as my last apple was the late 2012 Mac Mini and I have no money to buy even a cable for it now.
But I will say what I think either way.
If I had money I would definitely want to buy a new Apple computer. Something for video editing, at least 32GB of RAM, 1-2TB of SSD at a min. One thing I would also like is a larger than 24 inch monitor. Yes work can be done on a 24 inches, but I rather have the more relaxing feeling of a larger monitor for that workload. Something like Kramer's input on wider lanes. Hopefully with a different end result.
My point is, if I could buy one now and there was a 27 inch available, I really don't see me picking a 24 over it. IF of course there is no 27 at all, a 24 would do. But...why take 27 when you can take 24? No wait, it's the other way around.
No matter what happens, 27, 24, 32, 69, I do hope Apple actually has more colors than "political correctness silver or affiliated colors" for them. OPTIONAL. Also, if they do go for more colors, keep it lively on both sides of the computer? Not like the current 24" iMacs which are exciting in the back and prawn head like in the front. Keep it the same color on both sides. THE REAR ONE.
