If the answer is no, will you cancel your preorder?
No.....but I am very curious about whether I could sell my Voyager and not miss it that much, as opposed to selling other gear. I would not do that without having had it in my hands. I will only cancel the preorder if the demos turn me off. Barring that it is at least worth the potential of losing the shipping costs to try it with the possibility of returning it.
That's a reasonable question to ask.
I have not seen any indication of the Voyager oscillator design being used in The One. At least not like Grandmother where Moog Music clearly stated where each component was derived (VCA from Moog 902 module, filter from Moog 904 module, etc.). The VCOs in the Voyager, the Sub Phatty/37, and Grandmother are all different from one another, from what I've heard.
This may not even be a close comparison but if I had Mark's Memorymoog and his Voyager in my house, and I had to give one of them back, I'd probably give back the Voyager and be ok using Memorymoog do play leads, partly because, well the Memorymoog would let me play a wider variety of chords, and I'm not that picky about "authentic Model D tone". Ok, I admit the real reason is because of the cool custom LEDs that Mark installed .
