I am sure an announcement is coming shortly but RIM has updated their BlackBerry Messenger Social Platform SDK beta today. This new update also adds support for WebWorks developers which is VERY nice to see. So far the release notes are available in 7 different languages (no English version yet) so let me know if you can translate them. On the other hand they do have the BBM Social Platform guide for WebWorks developers in English.
You can download both from BlackBerry. Let me know if you see it officially drop!
