New details unveiled in a Press release:
http://arcadeheroes.com/2016/11/01/sega-resurrects-daytona-usa-with-daytona-reloaded-arcade/
-Name was changed from what was shown in Chicago (Daytona Reloaded) to Daytona 3 Championship USA
-47" screen
-27" billboard marquee
-Link up to 8 machines
-Camera with in-game avatars
-New cars and game modes
-Operator adjustable "party mode" for tournaments
-based on the original Daytona USA engine to keep the physics

Likely this means there will be two cabinet versions. Sega's last arcade racer was Showdown where they did a "Special Attraction" version with big screens, motion seats and a huge marquee and a standard version you would find in most arcades. Special Attraction versions tend to be made for theme parks and cost around $120-$160k; standard versions tend to be around $8000.
