I'm going to throw out my prediction. The control plates and lack of tremolo plate are to keep us guessing and talking.
I'm guessing it'll be the same body style as the private stock Brent Mason. The pickup layout will be similar to a BM except with an NF wound to JMs specs in the middle, bridge and neck humbuckers wound to JMs specs, all splittable with a five way switch that's wired up to the switching options that JM wants. Instead of the volume-switch-tone knob layout of the BM it'll be volume-tone-switch like the Vela or it'll be switch-volume-tone so that the 5way is easier to reach without the tremolo bar getting in the way.
This is how I'd design one. If they also build an S2 model of this guitar they wouldn't be able to keep up.
