@3DA, Finch Shfit controllers can be pre-ordered directly from Finch and should start shipping soon.
Per the Focus 6DoF Devkit, I know numbers of kits are ramping up in Q1 but I'm not privy to specifics of those details as I'm not on the Focus team and am a generalized support tech. I would defer that question to a member of the Focus team proper.
