*INDIANAPOLIS! This one is already confirmed from the released cover art, which clearly shows the famous tower at the start-finish line.
*INFINEON. Aka Sears Point, in California. Popular desert road course, and another NASCAR staple. Brief glimpse of it in E3 gameplay.
*DAYTONA??? Can't be sure about this one, but it would be a FANTASTIC addition, of course. The map clearly shows 2 tracks in Florida, and we know that the southernmost is south Florida's venerable Sebring, already a veteran of Forza. The 2nd one is in northern Florida, but the fan community seems divided on whether or not this is, in fact, Daytona, or just the similar but fictional Sunset Peninsula from previous Forzas.
*TOP GEAR TEST TRACK. Already well-documented in lots of videos, not to mention the show itself. Looks like Top Gear is working *very* closely with Turn 10 to expand Top Gear features enormously over the paltry bits they gave to Gran Turismo 5, making this one very authentic to the BBC show.
*SPA FRANCORCHAMPS. Site of the French GP.
*HOCKENHEIMRING. Site of the German GP. Brief glimpse of it in E3 gameplay video.
*GERMAN/CZECH TRACK. The map shows a mystery dot in east central Europe that hasn't been identified yet. Theories swirl around the Norisring street circuit in Nuremberg, the Red Bull (aka A1Ring) Ring in Spielberg, or maybe an F1 circuit in the Czech Republic like Brno or Masaryk.
The map is entirely Northern Hemisphere....I was sincerely hoping for some new tracks in Brazil and Australia, but they seem to be left out yet again.
Anyway, definitely excited to see some NASCAR tracks finally getting their due, and some more F1 circuits. Don't know if that means there'll be any licensing tie-ins this time, but I'm still hoping.
