I decided I'd try and be smart and go straight to the horse's mouth about this...What was I thinking?!
Here's what Samsung has to say about it:
"Dear Chris,


Thank you for your inquiry. Unfortunately, we are only able to provide information regarding models that are currently on the market for sale, as any pre-release information would be subject to change and could therefore be inaccurate at the time of launch. We are sorry for any inconvenience this may cause.

Thank you for your interest in Samsung products.

Sincerely,
Technical Support"

So the official answer to the SDHC issue is...wait and see.
