See the Statement from the Interim Chair, John Unsworth: http://bit.ly/qRzQzk
The is the most official information we have at this time, I believe (others will correct me).
Scrolling the thread "Changes on the TEI Board " (6 messages) I find near the end an announcement for

Please, where in the bulk of ongoing threads I can find that "full statement"?
