Thanks for the positive feedback. I'll try to cover all the questions in one post here.
"How's the walnut neck compared to the bubinga? Will wenge necks follow?"
Walnut is lighter, less stiff (hence the carbon fibre) and warmer sounding. It feels more "grainy" to the touch. The carbon fibre adds stiffness and prevents the highs from being damped. The resultant tone seems a little more fullrange (no Eddy I'm not trying to sell you one;)). Deep yet with sparkle. We have no plans for wenge at the moment.
"can you show us the back of the neck (so we can see the stripes)?
I forgot to take a photobooth shot of that, but I have a shop shot.
"The only improvement possible would be a matching headstock. "
Yeah, I was thinking the same thing

"So, does that mean the neck is now as thin as a Z series neck? "
No, Afterburners and Z/P's will continue to have their own distinct neck shapes, dimensions and feels.
"where is this going?"
At this point, I don't even know. There's a bit of a mystery brewing.
"How about the electronics? Anything different there? It looks like there's no Blue Qube.
One or two Mach II pickups?"
The electronics are the new standard. FD3 neck, FD3MII bridge. This combination pretty much makes the bluEQube redundant so it's been removed for the sake of cleanliness and simplicity.
