If you're interested in the final TR, I would imagine we'd list it on that page you linked. If you're interested in following the drafts before it becomes published, you'd fine them on http://www.open-std.org/jtc1/sc22/wg14/www/wg14_document_log... (A draft has yet to be posted, though, so you won't find one there yet.)
I can't ever tell if I'm looking in the right place. :)
