True ofc, but I think that that won't be before the release of Victoria because:
CK2 had three DLC's left when HoI4 came out (2 major and one minor, one major has been released now), so by that logic EU4 will have 3 left too when Vic3 is released (if it is released).
And that is leaving multiple possibilities out:
1. They make the converter a preorder bonus for Vic (like with EU4)
2. EU4 won't follow that logic and will have an presently unknown amount of dlc after the release of Vicky...
3. It is released as Victoria dlc (select the savegame, game will find the EU4 folder itself)
4. It's added as a free-lc (as should have happened for the EU4 converter as €10 is not cheap for a converter that works like it presently does, even if it'd gotten some love last months) even if they stopped development like that random patch for Vic2
