Well, I believe that they mentioned that their goal is 2 Ferraris per year, but there is absolutely no info what the secon one should be. Me personally, I would love if they made Jim's P4/5. Then you can have a "then and now" pair.
I have confirmation that there is another Ferrari model that will be announced and shown for the first time in Germany in February. I can't divulge which model but it will be a race car from the early 70's.
