O.K., for those unable to actually read the linked blog text or drawing, the official word is the S3X will use the same 9 spline cog pattern that Shimano has used on their freehubs for 25 years. SA is showing 12T and 13T cogs, other companies already make SS cogs in other sizes for the Shimano 9 spline pattern.

Rumors out of Interbike were $150 USD for the hub+cog+shifter, available "early 2009".
