Just a caught a new developer post on the Matrix Games forums.
MWiF has now been delayed release all the way to July 2008. The developer doesn't feel he will be able to finish his work until Christmas time 2007, and then the game needs to go to printing and distribution.
Needless to day, a lot can happen to a project over the course of another year. Fans were already given three different release timelines in 2006 alone. I no longer have faith in this project.
I suggest players assume that CWiF will be the VASSAL module for a good long time to come.
