Well, it's still nothing definite. More like some "dialog" relatively to previous images looking similar. Take note of the upper-left chip's pin #1 getting moved, plus anotations about a 2-sided PCBoard "X-Ray View" for a few right-side counterparts. Observe how the bobins density practically doubled, allowing hopes of further miniaturization, possibly by using shorter U-Cores to raise the power cells and hence free a long storage compartment for the "tool", etc. Not to mention my preoccupation for persons a those with visual limitations, in this case adopting a type of mechanical 2-digits (binary Yes/No) "key" encoding that they can read through the tip of a finger, so they can differenciate between specialized-application tools too.
