Equally, I think those who really needed the video functions that were removed when Quicktime died will have already moved on to using other products. It would however be extremely convenient to be able export (render) a region of video between the loop markers complete with audio for use as a quick demo!
Whether video export should really be one of the top priorities is debatable, especially considering there are already plugin solutions such as VidPlay/VidRender. Similar arguments apply to (3) chord detection, anyone who really needs this will already be using Melodyne. Should Steinberg development resources be wasted re-inventing the wheel? IMHO it would be better to improve the ARA2 integration to achieve the same thing.
In that list, also I see an emphasis on fixing and enhancing existing features rather than adding new features.
