Let's seriously think about Pikes Peak though. Some arguments why it's possible:
1. Definitely fits the "somethining to talk about". I'm sure a lot of people will be really happy about it, but people, who prefer racing their Gr3 and Gr1 and waiting for more real-world race tracks, will probably not be so happy.
2. Obviously, PD's exclusive license for Pikes Peak seems like a guarantee the track is gonna appear.
3. We have plenty of Pikes Peak cars in game and they even have a separate subcategory.
4. That one Scape we saw when Suzuki VGT was announced. The same Scape was also featured in their media post about Audi Sport quattro Pikes Peak car. Usually, when PD add a track, in the same update Scapes with that track get added, so maybe that one Scape is just waiting for the track? They even had a chance to add it in their Colorado pack a couple of updates ago, but it's not there.
5. That whole Hyundai collaboration, which so far only gave us a car (with Pikes Peak visual modifications).
But there are also reasons to doubt all that:
1. GT7 is not GT Sport, but eSports is still a big thing, championships are still going on, and you can't really use Pikes Peak for any of that. Not only it's point-to-point, but also pretty narrow to overtake. So would they spend a lot of time working on a track which won't be usable in that aspect, rather than something more traditional?
2. "Never say never", but they got the license even before GT Sport was released, it's been over 8 years at this point. And yet, it was never properly hinted at by PD. They keep dancing around it, saying Pikes Peak this and Pikes Peak that, but nothing even remotely like "look forward to try it yourself in the game in the future!". That track was also never mentioned in any datamine, as far as we know, so it doesn't look like they are working on it (unlike Lake Lousie, for example).
3. Regarding the Scape, I think it's possible they for some reason only have one from there and simply forgot to add it. Or maybe not even planning to add it, they have a rich history of keeping insane photomode locations to themselves.
4. How exactly would they even implement it? Current rally tracks have invisible walls and mesh-looking concrete barriers all around, something like that for Pikes Peak is not going to feel right. And does GT7's physics takes elevation changes into consideration when calculating car's performance? Basically, I'm not sure if current game design choices work with that track.
5. Similar to 3rd point, but that whole Hyundai collab technically already happened last summer during the event (?). And if the track is actually coming out now, it should've been already in the works when the collab happened. Would make perfect sense to do some sort of a tease during the collab, however, didn't happen.
