Am I the first person to point out the size of the 8x fixed vs the interchangeable 2/3?
8x may be smaller then the d3 from the front, but it's at least twice as deep! And deeper then the 2/3 interchangeable by a third.
Batt module built it, I/O module Built in... Seems like a lot more of a package, and a lot less of a brain.
