When Nikon is offering to early review a pre production lens, I believe the production is already in full swing.
Its not a prototype - I believe.
A prototypes can still be modified. Why would Nikon offer to early testing if it might be changed? IMHO prototypes and productions are identical in performance. The only difference is the serial numbers
