Yep. A friend of mine a couple of weeks ago was involved in testing 3T disks 
available now in RU: 

- Hitachi Deskstar 7K3000: HDS723030ALA640
- Seagate Barracuda XT: ST33000651AS
- Western Digital Caviar Green: WD30EZRS-11J99B0

from which only the latter, according to the tests, uses 4k firmware sectors.
