Read that link more carefully. Advanced Media is launching their RITECH branded SDHC line, SSD cards, and two port USB Hub drive. The 16GB and 32GB capacity points refer only to the SSD (solid state disk) cards, not SDHC. Nothing earth shattering there, and considering the relative densities of the two form factors (the SSDs are sized like 1.8" and 2.5" hard drives), I'd be surprised if their biggest SDHC even matched the 8GB capacity leaders, let alone surpassed it.

I do expect we'll see 16GB (possibly even 32GB) SDHC production sometime this year, but we're not quite there yet.
