Making the Case: Professional DSLRs must have both SDHC and CF

In this new experimental feature, we pick to pick on a topic and open it up for discussion :) The first issue at hand:

"All professional DSLRs should be able to use both CF and SDHC (SD) memory cards. Professional means a versatile tool, and being able to use both CF and SDHC is a must considering the current technology".

We agree with the above statement, especially since we just wrote it :) Does anyone think that should not be the case? Please speak up, the comment section is yours :)
