Not really, the car is still in the development phase. There is no final production version for Polyphony to even model and we are not sure if Polyphony still has a good relationship with Ferrari s.P.a or if they are relegated to waiting for a Ferrari model to appear at a local dealer/seller/owner like many game developers have had to do.
The F12berlinetta seems to be a shoe-in since both Forza's Turn 10 and EA's Ghost Games/Criterion Games already have a modeled version in their games (Forza Horizon/Forza5/Need For Speed Rivals) and its absence would make PD look a bit silly. Not to mention the Kaz's Twitter thread (in the GT5 section oddly enough) showed that Yamauchi has been to Maranello this year which is after F12berlinetta production had started.
