I will start a new V4 thread soon to address all of the differences and options for what i have planned, there is a small laundry list of them. But yes, the V4 will comes standard with a "hybrid" armature. Basically a version of the wing mechanize in high density resin and a a partial alluminum armature.
The Mike Reader armature will fit this with little to no mods, in fact it will fit it better than the V3 as i have made the mounts for it.
Price will be adjusted of course if you opt for the Mike Reader armature (which you need to get from him) and opt out of the hybrid armature.
I have some cool options for the V4 that i will announce when I start the thread.
And yes, started some preliminary molds for the V4 today, I need them one way or the other for myself so why not....
