Now I won't say I know what the final two cars are (because frankly, I'm no closer to knowing then anyone else), but I do want you folks to notice a pattern with the Up-to-Date GR.3 cars added post launch for the already existing manufacturers: Every single one of them has a Road car.
- The Mercedes-AMG GT3 '20 has the Mercedes AMG Black Series its based on that was already in the game at Launch
- The Nissan GT-R GT3 Nismo '18 has the Nissan GT-R Nismo '17 its based on that was both already in the game from launch AND was added in GT Sport as well
- The Subaru BRZ GT300 was added alongside its Road car version
And what is one of the cars being added in Spec III? The Ferrari 296 GT3. I know I'm sounding abit silly but looking at what I have laid out, I think you'll see what I'm thinking might be one of the remaining unrevealed cars...
