Doing a bit of fishing last night amongst some of my contacts, it appears that the following is planned. Some of which we already know.
1) ‘Honfleur’ – Replaces ‘Normandie’ which moves to the Portsmouth/Le Havre route.
2) 3rd E-Flexer – Replaces ‘Baie de Seine’ which goes back to her owners.
3) 6th E-Flexer – Replaces ‘Cap Finistere’, unknown what will happen to this vessel.
4) Project Codename ‘Bretagne 2’ to replace ‘Bretagne’ – Official Announcement early 2019.
Please note, the final one is only a rumour. Not to be taken as official news. It appears that only one news site has reported the story about 'Bretagne' but already someone has jumped on it, posting it on social media.
