Henry Holt just announced their new policy of no response unless contacted by the publisher and to not send SASE's.
So, that makes three houses with this policy (Houghton Mifflin, Dial, now Holt). I do hope more will follow. No one needs to wait 13 months for a form and no one needs to send exclusively anymore. This step of throwing away unwanted ms's is a step toward a saner writer's world!!! WEE!
