As Nikon continues to build out their lens line-up for the Z-system, while maintaining the integrity of their current "cash-cow" (the F-system), I think it would be prudent for them to expand their line of "FTZ" tubes. Unlike Canon, who has declared the death of the EOS mount, Nikon has sent signals that the demise of the F-mount is not in the near term. As such, they could leverage both systems by expanding the capabilities of the tubes that conjoin the two.
Canon has integrated rear-filter slots into their tube and included a control ring, this would add feature and value to current F-mount user/switchers. Nikon could do the latter as well as a create a less bulky "E-Lens to Z" adapter without the aperture controls present in the FTZ. This wold make lenses like the PF-series and newer super-tele E's a tad less bulky. Finally, the "D to Z" converter with screw-drive connections is highly desired by those who still love their legacy AF glass.
In the absence of a quick release of treasured optics, this might breath life into the sales of both F and Z gear.
