I have no info about opsjoner... . I think from the start it was 2 firm + 2 opsjoner = now 4 firm.
1) POLARIS, ca. 300 cabins, 1500 Pax
2) ORION, 433 cabins, 1785 Pax
3) VIRGO, 433 cabins, 1785 Pax
4) N.N. (i guess also here the bigger solution with more cabins)
Because the fleets from GNV and Moby are much overaged they would need a lot new-buildings more, but i think (and hope) they will develop another design with more cruise-ferry-standard.
They have operated many routes now since decades with very high comfort-standard onboard, competitor Grimaldi is projecting very luxury new cruise-ferries - so normally GNV need also now much more than "normal" Ropax-standard for futher newbuildings for to replace all the older cruise-ferries.
As said here 28.june - if only GNV want to replace all ferries from last century they would need further more 11 (!) new-buildings. Number 12 could be a replacement for the 2002 build La Superba which will goes to scrap soon after fire onboard. And if they would place the order for these new-buildings in 2025 deliveries could start in 2028 and would takes 6 years... .
And the sister-company Moby Lines (same owner as at GNV in background) would need 4 big and 4 small cruise-Ropax-ferries normally for to replace only oldest ferries from the 70ies (ex DFDS) and 80ies (ex Color Line Christian IV)... .
So they could also together order 16 (!) new biggest Cruise-Ropax-ferries now - and if the last is delivered in 2035 then they would have again the 200X built ferries (Moby Ale Due, La Suprema, Moby Wonder etc.) with an age of (much) more than 30 years - not possible to replace them with these THEORETIC 16 more new-buildings... .
All GNV ferries in 1 video, look at the partly crazy rebuilt funnels with scrubbers:
If we compare here the Pax/cabin/car-capacities with the newbuildings - the new ORION, VIRGO and N.N. could replace ATLAS, CRISTAL and BLU with ca. 105%. And the new POLARIS the old GOLDEN BRIDGE... .
But anywhere was to read that they shall go on the route Valencia-Mallorca.
Interior and sundeck Shiptour from the newest in 2003 built ferry LA SUPREMA shows in details the cruise-standard of the ferries, but also how much worned, downrunned and used the fleet is - i would not accept a cabin as this front-family-suite... . They have daily more than 2000 people onboard - but this is to see also... . And a shame that all pools on all ferries are not in use. (put off the sound better)
