Yep, pricing will be high and it will take a pair of SLI Titan XPs or 1080Tis to drive it.
But 2018, the second iteration of this should see a larger panel with some of the issues that this one will present resolved. Yes, make it in 32 or 34 inch and I will need to get a wider room with a wider desk to run three of them.
The 32" 4k 60hz Gsync Acer was $1200 at launch i believe, i actually see it going for more than that at some places. In any case this monitor will be between $1-2k for sure. I won't be buying because IPS, and 27" is too small for 4k.
