David, I emailed Montbell(MB) and the reply from the head office in Osaka was Spring of 2007. I considered waiting for the 800 fp bags, but bought the 725s instead; I use them around the house as comforters when I'm not out camping.
The outlet stores here in Japan have the alpine (zipperless) down bags starting at the equivalent of $110.
Thank you for your inquiry.
The sleeping-bag will be a sale schedule next spring.
Please wait for a while.
