We have witnessed the Oxygen OS on the OnePlus One just a couple of days back.
If you haven’t tasted the Oxygen OS then you can have it here:

If you are unsatisfied with the Oxygen OS or you are really in love with the CyanogenMod and still waiting for this to come then yes you are lucky enough and I will suggest you to wait for couple of days more.
See the below OnePlus forum link where Steve Kondik (CEO of Cyanogen INC) had a conversation on Google+ over the release of CyangoenMod 12S:
Steve’s Google+ conversation
where he says that the delay is because of the changes made in Google’s test suite and the Official CyanogenMod 12S update will be pushed via OTA to the users when they will get the mail from Google.
