I think it hit Oakley.com at midnight PST. I bought mine about 6am PST and it was available for several hours after that before it was sold out (at least the first sell out before it came back online a few more times).
Documenting the differences between the SF16-C vs. the Carbon Prime to the end of 2017:
1) CF-injected O Matter - The SF16-C has both upper and lower potions of the orbital made of CF-injected O Matter, whereas only the top portion on the CP is made of it (the bottom half is regular O Matter).
2) Nosebombs - The CP has black Unobtainium nosebombs while the SF16-C has red nosebombs (or frosted clear in the case of the athlete prototype).
3) Lens etching - The CP's left lens is etched with "Prizm" or the MotoGP logo while SF16-C has the Scuderia Ferrari logo.
4) Earstem badging - The SF16-C has the Scuderia Ferrari badging on both earstems (or blacked out badging on the athlete prototype) while the CP has no badging.
5) Piston colour - The SF16-C comes with either silver or black pistons while the CP has only silver pistons (for now).
6) Earsock - The SF16-C has red earsocks while CP has black.
7) Icons - The SF16-C has Ferrari red icons on the earstem (black on the athlete prototype) while the CP has white, silver or red.
8) Nosepiece - The metal nose piece mount that holds the nose bombs is a slightly different shape at the portion that connects to the orbital.
9) Earstem laser etching - Each are etched with their respective model name and number. Some SF16-Cs will not have any etchings in the inside of the earstems.
10) Screws - The CP screws will be black while the SF16-C might be silver on some (especially at the hinges).
11) Serial number - Most, but not all, of the SF16-C have a serial number engraved on the underside of the CF-injected O Matter near the left hinge (in the form of SS123). The all-black SF16-C prototype and Carbon Primes do not have serial numbers.
