No release date at the moment. I've gotten quite a lot done the last few days though. Based on Actions/Conditions/Expressions finished I have done about 60%. But most of the time has gone to planning, creating the core structures/functions and modifying the Box2D engine to work well with MMF. So a release shouldn't be too far away.
The main problem has been implementing the new interface that allows you to modify/create bodies by referring to the Active Objects attached to them. It allows instant creation of bodies for all objects in a single event. This combined with all the features of Box2D has lead to quite a lot of code. At the moment it has 13 Conditions, 259 Actions and 123 Expressions.
This might have been a little off topic though... Sorry about that.
