Why would the Dev's request modder's models if SHIII is done

[Immacolata]

OK, thats interesting, but to you think that means that there will be no more SH3 stuff?

I really hope they could fix this big things in the game like wolfpacks etc. in a add-on as they have promised.

Fix big things like wolf packs? Please, I'd like them to fix IMPORTANT bugs and broken features first. Such as the ridiculous 8km visibility, the wonky spotting algorithm, the XXI boats, campaign oddities, a proper manual plotting method. Wolf packs is really only a hollywood feature which would lend no real gain to gameplay.
