Articulation

This is an update on the articulation section in the How the reviews are presented post, now also available in an improved version as a page.
Two potential articulation schemes, old and new, are currently under consideration, but most of the reviews only refer to the old scheme.
In the new scheme, every point of articulation is a ball&socket or peg&socket joint that allows for part swapping.
Articulation according to the two schemes is as follows:

Point of articulation (PoA)	Old (21 PoA)	New (up to 23 PoA)
Neck	Ball jointed	Ball jointed + swivel at the base of the neck-peg
Shoulder (x2)	Swivel + hinged	Swivel + hinged
Biceps (x2)	Swivel	Swivel (TBD)
Elbow (x2)	Hinged	Swivel + double hinged (for great bending)
Forearm (x2)	-	Swivel
Wrist (x2)	Swivel + hinged (for left wrist front-to-back movement and right wrist side-to-side movement)	Swivel + hinged (for left wrist front-to-back movement and right wrist side-to-side movement)
Abdomen	Hinged (usually for male characters only)	Ball jointed (the cut is at mid torso)
Waist	Swivel (in some cases a spring loaded torsion action feature may be present)	Swivel (in most cases a spring loaded torsion action feature will be present)
Hip (x2)	Swivel + hinged	Swivel + hinged
Thigh (x2)	Swivel	Swivel
Knee (x2)	Hinged	Swivel + double hinged (for great bending)
Calf (x2)	Swivel	Swivel (TBD)
Ankle (x2)	Double hinged (for both front-to-back and rocking movements)	Swivel + double hinged (for both front-to-back and rocking movements)

TBD → to be decided.
