The pre HL version had over 1350. Or do you mean the upcoming reduction one?
As for progress, I have the England, Ireland, Scotland, and Wales restructured for a 26% province count reduction. Currently at work in France, hoping to have the rest of the provinces done this weekend. My goal is to get the overall province count down to at least 1000. I suspect I will be able to trim quite a lot from Italy and Lotharingia (I have a lot of low # holding provinces in Italy and far too many normal manors added as castles in Lotharingia). I've done a lot of work on removing/adding/moving/renaming historical holdings to be a bit better. I have cleaned up and made new events and decisions (adding pictures to the events so they are no longer boring to look at).
Cultures will be broken up in the next version as well. It will be a test and I may end up drastically changing it in the version after if it doesn't work out.
I've got some really nice new coat of arms by
Oznerol which will also be in the next version.
I have added historical trade routes across the map but they seem to cause some major performance drop so I am trying to see if anything can be done with that or not.
Hopefully will have a solid version in 1-2 weeks depending on how much free time I end up having.
