I don't know, it still looks quiet WIP, at least the weapons look not so good, if you are familiar with the quality of FH2. I think they just converted them from Armed Assault 1 Invasion 44 mod. But they said somewhere, that they will slowly try to replace the old weapon models by new ones. Thatswhy you will find a new M1 Garand in the new version.
The new Wespe animation looks also damn good. I will try to gather some people to play the Coop missions, when the new version gets released. A working CTI or Warfare mission could also help the mod.
