Returning Original Tracks
-I think Apricot Hill could be fantastic as-is, with minimal changes needed (if any) for good online racing. It could even host a Roadster endurance featuring the NA, ND, and ideally the NB and NC if we get them - though I'd hope the NA-based Touring Car would be excluded.
New Original Tracks
-I still wonder if we could eventually see a new Colorado Springs layout, as the naming format for the location is the same as other locales that've received new layouts, such as Alsace and Dragon Trail.
-Similarly, I would totally be down to see rain at the Tokyo Expressway South layout, as well as hypothetical North and West loops. Also, could the change from "inner/outer loop" to "clockwise/counter-clockwise" imply a larger "outer loop" could be coming? It would certainly contrast with the Central layout.
-I'd say we could use more city courses, but I wonder if the relative lack of them could be due to the PS4's hardware limitations?
Returning Real Tracks
-Indianapolis is obvious enough, especially with the infield course that IMSA still uses.
-Twin Ring Motegi would be an obviously great addition to the Super Formula and WTC 900 events.
-Would the return of Sonoma be too much? We do already have a ton of circuits - both real and original - based in California.
New Real Tracks
-I swear, I'd go nuts if we got Lime Rock Park.
-I also think it'd make sense for GT to add more courses in other parts of the world, with Kyalami, the Dubai Autodrome, and Phillip Island coming to mind.
Returning Cars
-Would love to see the Ferrari SP1 again, given its backstory.
-Similarly, I think we could really use some returning models from Jaguar, like both iterations of the XKR Coupe.
-The 1999 Aston Martin V8 Vantage would be great, as I really like how it looks.
-The Nissan Fairlady 2000 would be a great historic addition, as would the Nissan Skyline (BLRA-3). I'd say the same regarding the original Nissan Silvia, the original Toyota MR2, the original Mazda RX-7.
-For Mitsubishi, I don't think it'd hurt to include the FTO, a later version of the GTO, and the Lancer Evolution IX. Maybe even the Lancer Evolution VIII alongside the IX.
-Where's the Lamborghini Gallardo, anyway? Maybe we could also get a premium version of the Diablo GT-1.
-I know I speak for a lot of people when I mention the JGTC GT500-spec Honda NSX.
-Man oh man, we could really use more TVRs, with the Cerbera Speed Six and Cerbera Speed 12 immediately coming to mind.
-I think the Fiat Coupe is really neat, and on that note, the Abarth Grande Punto should return as well.
New Cars
-I didn't have the best idea of where to start on this, but I'll start with some automakers I had in mind. For Pagani, that's easy - I'd have a Zonda F get added, instead of one of the older Zonda models we've seen in previous games.
-For McLaren, I'd add the "normal" P1, the Speedtail, the Senna, the 750S, the 720S GT3 Evo, the Solus GT, and the Artura.
-As for Ferrari, I could go on for a while on this. There's the LM24-winning 499P, but also the super-rare Sergio, too. Not to mention the classic 360 Modena. The 296 GT3 and its road-going equivalent would be a great modern replacement for the current 458 GT3.
-Lamborghini? I really want to see the SC63. But I also want the relatively more common Miura S, and the original 350GT. Then there was that Espada that supposedly got scanned. I'd also be down to see the new Revuelto, and perhaps a pre-facelift Diablo SV.
-More Maseratis would be great, too, with road and racing versions of the MC12 being potentially great additions. Maybe the MC20 GT2 could even fit in as a Gr.3 car.
-Speaking of Italy, I would really, really like to see the older Fiat 124 Spider that was designed by Pininfarina, perhaps alongside the newer Abarth 124.
