There's been a hold up with the beta/final patches that's for sure, it certainly has put a big hold up in a 2 part campaign I've been working on. Every mission had to have several tweaks if not complete rewrites if not scrapped
Huninthesun has released 2 campaigns since final patch, I've released 1.
There are several campaigns done by the Russian community
and I'd hazard an 'educated' guess there are 2 campaigns on the verge of release
Would be good to see a few more people getting involved in mission/campaign building tho
