Not sure if anyone saw this, but SDXC is now in the wild. And with Fat64 available from Microsoft, it means that our devices will be able to start supporting the new cards soon. Well, not *all* devices, but certainly those with the proper software onboard to do so. Either way, now that the standard is final, I expect to start seeing the first 64gb and 128gb SD cards available by Q4 or so.
