As explained previously, the expansion will take lot of time to complete.
To avoid a too long wait for the remaining OFP fans, i have decided it would be a good idea to release some of the planned expansion features and some surprises in an official upgrade.
This way i can continue to work on the expansion, and meanwhile the players will have new and improved things to play with in WW4.
You can always follow the various development of the WW4 modpack upgrade 1.5 in this thread on the Bohemia Interactive board :
You can watch some videos of few new features in the work that will make it for the WW4 modpack 1.5 release on this youtube link :
Don't worry, the waiting should not be very long before the release, the upgrade 1.5 is progressing very nicely.
