In the meantime, if you're brave you can peek at the raw session notes: http://etherpad.wikimedia.org/mwhack11Sat-Parser
We're reviving the wikitext-l mailing list for people interested in the project; it's gotten some traffic about interesting projects but we'll be making it an active working group. I'll also be making regular posts here on wikitech-l, on the Wikimedia tech blog, and on the wikis -- but I don't want to clutter wikitech-l *too* much with the nitty-gritty details. ;)
Project hub pages will go up tomorrow at http://www.mediawiki.org/wiki/Future
