As far as I've been able to find, Hal Abelson's last statement was on May 13, when he wrote that the report would be released "this summer".

This is indeed much delayed from his initial statement on January 22 that he hoped the report would be ready "in a few weeks."

It's disappointing that it's taken this long.
