We have already forwarded all feedback, both on the matter of production vehicles on the Vautour IIN long before the premium replacement was even mentioned and we have again relayed those thoughts based on some recent constructive posts from @panzerknoef and @Cedjoehere:
The developers do already have some considerations for the Vautour IIN within the standard branch too, however it will not be with this update. Primarily because there is already the Mirage 5, Seafire III the IIN premium replacement was planned for this update due to the replacement being necessary for the release of the Israeli tree which we already said was coming.
The main priority air wise for the French tree is a new top fighter aircraft, followed then by considerations for a IIN within the tree after this point.
