Sadly I think Iron Front (WWI) is never going to come out. That really only leaves In Country: Vietnam as the only hope for RO1 fans.
The UDK was released about a month ago. You don't really think a mod is created in a month, right? The only thing they could do is create textures and static meshes. All the hard stuff like rigging and coding come afterwards, which takes a long time when everyone is volunteering their time.
