I have asked dealers and they said it will be priced similar to the 500 S&W since it is a limited edition run. So, the final sales price will likely be in the $800 area.
It looks like the 57 Mountain Gun (Link to S&W Here). The Scandium Frame, Titanium Cylinder models are going for around $678 on GunsAmerica. A NIB carbon steel frame should go in the $600 - $700 range. Post the question over at the Smith & Wesson Forum and you will probably get the going price.
