More or less what I'm expecting. Worth noting though that in that show it always felt like Smallville and Metropolis were at the very least in the same state. Even characters without superspeed seemed to bounce back and forth like it wasn't a big deal.
In Earth Prime, Kansas and Metropolis are apparenly looks like Metropolis is in New Jersey and we know Smallville is in Kansas. Obviously not a problem for the Kents/Lanes, who can just whoosh over there or have Clark whoosh them over there. But you probably shouldn't see say Lana randomly dropping by the Daily Planet or Perry, if he's still around, casually visiting the Kent farm.
Also Arrowverse Gotham is in Wisconsin? Never pictured it there, but sure, why not.
