You gotta give it to Neural DSP though... The marketing campaign works wonders. The pre-orders are coming in massively with the first 1000-unit batch being sold out. A lot of Kemper owners, including forum users, pre-ordered. And look at how much we're talking about it!
Imho, this shows that a lot of guitarists are feature hunters. I don't necessarily mean that in a bad sense. I think that our needs are evolving and so do our expectations.
Featurewise, the quad cortex definitely is a 2020 machine. The screen (touchsensitivity, size, resolution), the editing possibilities (with the integrated wifi, desktop and smartphone editors) are ahead of the competition (especially the Kemper). The Kemper editor is nice, but could be better (Having a dozen of knobs for a graphic EQ is just weird). And the screen on the profilers and remotes are just terrible.
The Kemper looks like an early 90's machine. But boy, does it sound good...
I'd also mention the integrated audio interface, but the Kemper is pretty much the only device not having an integrated interface. Having to buy an audio interface was really painful for me at the time. However, I'm so happy with my interface now and I use it for plenty of other stuff. Also, it gives me flexibility for the future. I'm currently tempted to go Tube Amp with integrated Load + IR (like Suhr PT15, or Hook Wizard). I played with more tube amps recently and I really liked the experience Having the interface would allow me to sell the Kemper without having to buy an interface...
Regarding the cortex, I'm not buying something that I didn't listen to. Because that's the most important factor when spending 1.6k on a piece of equipment, isn't it?
On a more personal note, the workflow does seem to be more on the tweakier side. I'd probably tweak for hours to get "THE" sound I have in my head (or an even better one). Currently, I just want more simplicity and I'm not excluding going back entirely to tube amps (with the IR thing).
Let's see what time brings... Maybe the reviews are going to be amazing and I'll get one. One thing is for sure: it's exciting times for guitarists. Lots of new products and certainly more than enough tools to sound freaking amazing !!!
