Why would they lower the resolution? It's already "low" (non-4k, non-retina)?
Why would they lower the price? People are still buying the current one in notable quantities (which I consider insane while at the same time I sometimes have to restraint myself from pulling the trigger on one myself...).
They are available in the channel with a bit of a discount, but still...
So, your hope is, IMO, delusional at best. Sorry to put it like that ;-)
For people who do non-graphics stuff, the resolution isn't low. Most TVs have a much larger size than 27" and are far from being 2560 x 1440. Apparently everyone is buying them and nobody really needs much more. If you're buying a 4K screen and you're not into video animation or graphic design stuff, it's just a waste of money. Well unless you are an absolute fanatic about movies and I don't know what, but even then it wouldn't be really that useful as most movies are far from being made in 4K.
For me - someone who uses his Mac for music production - it would be useless, and the current resolution is already probably more than I need.
And about the price of the Thunderbolt: It seems like the 27" Cinema Display has a higher value than used Thunderbolt Displays - I've been searching for a 27" Cinema for a while (now I finally have one) and thus I've also seen the prices of the Thunderbolt. The Cinema is always priced higher, probably because it's more wanted because of the lack of Thunderbolt on many Macs. I've seen Thunderbolt displays not even a year old for half the price of what they cost new. My Mac Pro doesn't have Thunderbolt so I had to pay a hundred more for a Cinema Display that's now almost 5 years old. I'm curious if it will retain its value.
But anyway, if the price drop on Thunderbolts is so huge, it usually means no one wants them, thus no one buys them anymore.
I don't think we should exclude a resolution or size drop. I mean, I love the current resolution and size - it's perfect for me. But the 30" was bigger in size and bigger in resolution too, and yet they released the 24" Cinema Display, and later also the 27". Never say never I guess
Now it's fine I have my display already. I would just have preferred to buy a new Apple display. Which wasn't possible because my Mac hasn't thunderbolt. One thing is certain, if the Cinema Display still existed (new, for sale) then plenty of people - like me - would be buying it instead of the Thunderbolt display. Apple is loosing on money here
If they release 4k displays only, even less people are going to buy them, because they will have an extremely high price, and most people know that 4K is simply a waste of money for them.
