Hi Lance, I don't have an exact date yet but it's not too far off. Right now it looks like there will be 2 more beta releases though before it will be complete.

Users who own version 3 can use the v4 beta right now from http://moi3d.com/beta.htm and there is a list of all the beta release notes at http://moi3d.com/wiki/V4Beta .

Also anyone who has purchased V3 within the past year or so will get a free upgrade to v4.
