About new circuits, based on some traces, it is possible to infer some things. I'm not saying these are real indications, but possibilities.
Firstly, we have the datamined information of the Red Rock Valley, Grand Valley and Tokyo R246 circuits, information that also brought Trial Mountain, Watkins Glen, Deep Forest, Daytona and Atlanta, tracks that were confirmed in GT7.
Second, there's the vestige of Apricot Hill in GT7's launch advertisements. So far we have no other information about this track.
Thirdly, we have Yas Marina being presented by Kaz Yamauchi, in August 2022, in a lecture at CEDEC, on how to idealize a racing circuit. It is very suggestive that they use this circuit as an example alongside Suzuka, when they could use another real circuit that is already in the game, such as Monza or Interlagos.
Fourthly, we have the Hungaroring. The real circuit had already appeared, partially, in a clip of the Gran Turismo Sport championships in 2020. Today, the same circuit is used for the filming of the Gran Turismo movie. So, it is possible to infer that PD-Sony must already have some commercial agreement with the Circuit Administration to launch the circuit in its video game.

@Tidgney has heard rumors from key people that Zolder may appear in the future of GT7.

@wbhumphries claimed before Road Atlanta's release that said track would appear in GT7, just like Sebring. He said this based on a source. Road Atlanta has been confirmed.
That's what we have for traces. I said traces, not evidence. Others point to Sugo for the circuit being mentioned in the game's historical panels. Others say that Sebring is possible to appear due to the commercial agreement that PD closed with Michelin and IMSA, on which I have no way of knowing the influence of this.
So, we have as possible circuits for the future of the franchise.
