At the SCA in dublin (euro siggraph conference) Jos Stam is doing a talk on unified dynamics slovers, with demos, which I would think is going to be nucleus for the rest of dynamics, muscle and the updates in Ex1+2 will be in there.

But I would wait till siggraph anouncements before commitiing to anything as thats the time of any major updates this far in the year.

Haven't a clue what will be in unlim or complete though.
