Even the update is unclear in that it refers to Fusina as Marghera when it is really Fusina-Marghera.
It also says (currently)-
The old Stazione Marittima port is still used for embarkation/debarkation processes for passengers starting or ending their cruise in Venice.
With the opening of the new terminal that may well no longer be the case.
There is so much confusion about Fusina, which I find very odd. Even Cruise Critic appears to be out of date.
Fusina is a regular question on the forum. Some look at Google maps, and see that there is a bus stop, then don't follow through to trace the bus timetable, only to find that the bus is only for workers shift times.
It is a very inconveniently located port, but then are some of the biggest cruise ports in the USA which often have little or no public transport.
But yes, in a way you can understand the time lag between the terminal opening, and the publication date of the book, but not to mention a terminal was being built is a bit of a surprise.
What is especially interesting is that for a time, various sources suggest that ships were also docking at a different dock at Marghera as well as at Fusina. Maybe the new terminal has consolidated all movements at Fusina. At Marghera berth taxis couldn't apparently even reach the industrial area. Whereas Fusina is also a ferry terminal for the passenger ferry to Patras (Greece).
So we really need up to date reports from people who have arrived and departed Fusina on various lines, as they probably all differ.
