The three other logos are Super Speedway GT3, Grand Canyon Mini and Piazza del Campo.
I only expect fantasy tracks, I would think any real world additions would have been promoted or even leaked since licencing would be involved.
I honestly, no matter what we get, will probably just continue as I do now driving the Nurburgring circuits all the time.
