I would love to see a new ibigger Mac option at 32" or even 30". Whether this would be a third size (21/27/30+) or a revamping of the two-size (24/30+?), I don't know. It would also create more interior volume (bigger GPU card?) and surface area to disperse heat, but might also allow for that ever-important "and it's .5 mm thinner." How likely is a bigger screen? And what resolution would Apple go with? Personally, I think a 5k 27" is overkill and would be happy with a 5k 30 (which is still about 200 dpi) or even 5k 32 (184 dpi). I don't see Apple jumping to something like Dell's 8k 32", but I also don't see them offering less PPI on a "pro" 32 than their 27". Seems like they'd have to engineer some new panel resolution/size. That seems unlikely, but then, Apple's getting back in to the display market, so perhaps.
