I've been hearing about this in increasing frequency lately and I just wanted to be sure that the OEM's (like blackberry) aren't blowing smoke when they say this. Supposedly on the latest blackberry they're claiming support for 48gb microsd, and another is claiming 64gb microsd. But they're not claiming up to 32gb sdhc, and up to 48gb SDXC, or 64gb SDXC. They're claiming 48 and 64gb SDHC!

From what I understand, the SDHC standard was cut off at 32gb. Is there something that I don't know, maybe a change in the standard limit, or are these guys just blowing smoke to sell more devices?
