My cameras, back to the K10D, support SDHC to 20 MBps (SanDisk Extreme III). The speed difference, in the camera, between the Ultra II (which is a Class 10, or nearly so) and the Extreme III is quite clear.
IIRC, Class 10 = sustained write speed of 10 MBps.
Are you referring to *ist systems or some card capability other than write speed? Card speed is, in part, a physical issue (electronic circuitry) and not necessarily fixed with new software.
