GSuite is evolving to Workspace, so prices and TBs too

I just filled in the form to be contacted by the Google Workspace Enterprise sales team and, just after clicking the "submit" form, I received a mail from Google saying that i will be contacted soon. Also it says that the subscription to Enterprise will include 5 TB of space each user.

Just to understand: the unlimited is dedicated to existing Suite users or it says unlimited here and 5 TB there to eventually limit the space in the future???
