But the pre-release artwork makes the keyboard look like it has the low-travel, loud, and very prone to failure keys that the new MacBook and MacBook Pros have.
As far as anybody knows its just a space-grey version of the "Magic Keyboard with Numeric Pad" released earlier this year.
If so, it uses a "scissor" mechanism as per earlier keyboards and not the "butterfly" mechanism in the 2016/2017 macbook pro.
However - I got one with my new iMac in the summer and it is
not the same feel as the old aluminium wired keyboard w/numeric pad: the travel is noticeably shorter (you can see that it is lower-profile) the feel is less "springy" and the whole keyboard sits at a shallower angle. There's no reason it should have the same faults as the MBP keyboard - but conversely its not the same tried-and-tested design as the old keyboards.
Keyboards are subjective - I found it OK, but not as nice as the old alu keyboard, and since I had a couple of those knocking around, I went back after a month or so: I don't see wireless as must-have in a desktop keyboard, plus the wired keyboard has a handy 2-port USB hub. Its a pity they discontinued it.
Reality check: with a MBP you're stuck with the built-in keyboard - at least while using it as a portable. With the iMac Pro, if you don't like the keyboard then just dump it and use any third-party USB or Bluetooth keyboard that takes your fancy. Its not even like the regular iMac where you have to pay an extra $30 to get the numeric keypad...
Since the "space grey" accessories are exclusively available with the iMP, I'm sure you'll be able to name your price on eBay if you want to sell your Magic Keyboard. Probably worth getting a trackpad as well
