I listened to it live earlier today, nothing new at all.
Repeat after me: "Over 700 cars, over 30 locations, 4K, HDR, and GT2 RS"
Ooh so all the "Stay Tuned" and "No Comment" features from E3 have been cancelled? Damn I was soooo much looking forward to those since they seemed to be the very core of the new game and appeared in every section of the game!
Maybe the next installment then :
Forza Motorsport 8 - The Stay Tuned Edition
