If that is the case (schematics be tweaked), so we can build our own preamp - then this is a possible buying factor for me.
Then again, the "cloning technology" might be a huge competition to the (somewhat discontinued) Line6 Variax technology. Even if it's very simple currently (no chance to change pickup position, etc - at least it wasn't shown in the video), it could result in a revolution on the market. Especially if you read comments about Variax guitars acting up. In this case - you can use whatever guitar you feel like!
The whole engine also seems to respond way faster (as can be seen with the RIR2 module - and that alone sounds great and looks intuitive IMO! A competition to TwoNotes Torpedo WoS?).
I'll have to see if I still have that old MKII SE license lying around. If that is the case... 129USD to (currently) MkIII.V is affordable. Maybe the prices remain the same for Mk IV.
Now if I could play guitar as well as I can handle plugins and recording/mixing gear...
