For past gt circuits, grand valley, autumn ring and ss route 5 (even though i think the existance of tokyo xpress might make it dificult) are a must. I would also like seattle (i miss thoses jumps) pikes peak, rome, cote de azur, top gear circuit, citta di aria and costa di amalfi back. Silverstone and indianapolis and somona (witch was called infineon when it was in gt) but i dont know if those would ever come back.
I dont think midfield will be back, it was inspired by suzuka. Once PD got suzuka in gt, midfield was kinda put aside. As for apricot hill, i would love this circuit but i find kyoto a bit similar in form.
As for new circuits, i would love hockenheim, watkins glen, circuit of the americas, mugello, sebring, macau ( the one where sophia floersh had her infamous high speed crash) and portimão (im portuguese ofc i would love this one).
I dont like gt7 rally tracks, please bring more rally tracks, new of from gt past.
