There was a guy on TV yesterday who said he had waited in the PreCheck line for 45 minutes and it didn't move, then he was being taken in a small group to the security place that's used by arriving international passengers with onward connections at MSP. I think he might have had CLEAR too, but it wasn't clear.

ADDED: My itinerary for next week has a very mild notice about the MSP security changes, basically saying that it's now PreCheck South and everyone else North. There's no mention of possibly needing to allow more time or get to the airport earlier than usual.
