Already on the drawing board.
Remember folks, we made Clio 1.0 under the assumption there would be a hard limit on province numbers. Had Xie and I known we were making a mod that would not have to deal with that issue, many areas of the world (esp outside Europe) would have been more detailed. As of now, Paradox most likely have more pressing developmental issues to deal with than any further tinkering with the map, I think it would be best to accept the map as it is rather than ask for more changes, with the exception of obvious mis-spellings of names.
Right now, one of the things I am working on province layout for
Clio's Iron Heart - a map mod being developed for HoI3. For Clio 2.0 for Victoria, my thoughts are something about halfway between what comes out in the commercial release for V2 and what we're planning for Iron Heart. It definitely will not have all the provinces that an HoI3 map would have, as that would probably kill most computer processors, but especially outside Europe (and some tweaking inside Europe) more is planned.
