The White Fox keyboard seems to be revered in the mechanical keyboard community. I would buy one immediately if it had backlit keys and, preferably, a function key row.
The Text Blade may change me, but right now what I want is the Apple keyboard (or something close) layout in a wired backlit version. I am typing this on a wired Apple compact keyboard on a Linux workstation. I have a row of LEDs above my keyboard tray due to the lack of backlighting. Note that Apple has not made this keyboard for many years, luckily I found two "new old stock" units before they were gone.
Currently I prefer separate cursor keys, but I did use the original Happy hacking Keyboard Pro that required chording for the cursor keys on a Sun workstation for many years. So, it will be interesting to see how I feel about the Text Blade once it arrives.
In any case, considering the hundreds of keyboard layouts that exist, it is difficult for me to understand why someone does not make a quality (I think that I do have a flimsy cheap version) wired mechanical version of the Apple compact / laptop keyboard layout with backlighting. I am hoping that WASD/Code will make one (I have a "tenkeyless" Code but it is too wide to be comfortable and fit on my keyboard tray with a mouse). However, maybe I will become a Text Blade only guy and live with some LED lighting for night work.
