OCZ was for the most part bought by Toshiba.
I'm not sure how public this is, but there were many more Barefoot controllers made and tested and a number of the later-generation OCZ drives were based on a much newer Barefoot-based controller.

But it's a dead end and last I heard Toshiba doesn't plan on doing another revision of the silicon to update it with anything like support for SATA link power saving modes.
