With a bit of humor and much appreciation to the community and all the teams that worked on the new UI, Alvin Reyes presented this final UI demo and slide deck (before Sites 9.5) to the Tridion Meetup on March 5, 2020 at the Trivident office in Amsterdam.

The Tridion Sites 9.5 new user interface is focused on the daily editorial experience and will be released next to the soon-to-be Classic UI, meaning existing GUI extensions and functionality will continue to work. Some actions and screens will only be available in the Classic UI in the 9.5, though we will continue to introduce existing and new features into this new UI. 

Here's a screenshot of the work in progress for the Content Explorer. Details and features subject to change.
