I don't take credit on finding any of these. A contact of mine was snooping through the text resource data for Scapes of
Gran Turismo Sport when they ran into these:
The multiple entries inside the resources are for various different points (such as different corners) around the particular scene, in this case the two courses listed above. The fact that the two courses which appear here,
Watkins Glen, which has an entry in the database for Version 1.61 of GT Sport, and
Albert Park, which was recently spotted in a marketing video as "just a decorative picture frame", supplements their possible inclusion for Gran Turismo 7.
The same can be found inside the Japanese language text resource files for Scapes, although using a different ID:
In addition, two Scapes entries were found for Daytona International Speedway:
Furthermore, two Scapes entries were found for
Circuit Gilles Villeneuve, a course which has yet to be seen referenced from any other data inside the game:
This is not definitive confirmation by any means, but there's multiple pieces of evidence scattered throughout that makes me think that both
Albert Park and
Watkins Glen will be showing up for GT7, maybe by tomorrow. There is yet to be anymore evidence found for
Circuit Gilles Villeneuve.
Road Atlanta has been spotted inside the database a while back, but no Scapes resources have been found (yet).
