I'm pretty sure the vast majority of parking will be surface lots...and if you don't want to sit in traffic, you can always head down to one of the local watering holes after the game for a pop or something.
I think the whole game day experience will be vastly different at PBA, since it's not located out in the middle of BFE where you have no choice but to pack up and sit in a ridiculous bottlenecked traffic waiting to escape State Fair Park. Some will go right home, some will walk over to a bar/restaurant for a bite to eat, all will find much easier egress than what we've been subject to for decades at State Fair Park, IMO.
