I've been focused on Apple display products for the past few months as I'm looking to make an upgrade from the Dell P2715Q 4k 27" I use primarily for development.
There is a three page thread on using the Apple 32" XDR for software dev on MacRumors. [1]
I believe there is a major product gap at Apple right now in the mid-market display. Specifically a replacement for the LED 27" Cinema Display which was announced 10 years ago next month. [2]
I am speculating that Apple could announce a new 27" 5k in part because of the rumored announcement of a new Mac Pro but also because the build quality of the LG 5k Ultrafine is just not great and there are obvious synergies with XDR production and Mac Pro.
I think this should be announced at WWDC is because developers specifically are being left out of good display products and Apple should be looking out for what they stare at all day.
While there are no supply chain rumors of such a display, I wargamed what this product might be and its pricing anyway.[3]
In short, I speculate Apple will release a 27 inch IPS display, 5120 x 2880 @ 60Hz with standard glass at $1999, Nano-texture Glass at $2799.
I had not paid a lot of attention to the refresh rate, but it does seem like kind of a miss that the XDR does nor offer this.
