MSP-XXX (Domestic), where would one find BE seats?

I've done a good amount of looking and I have not seen any lie-flat or cradle BE seats on ANY domestic bound aircraft out of MSP since DL took the A330 off the MSP-SEA/LAX routes. Anyone have any idea?

Also, any one know when the 767s that are currently on MSP-SEA and MSP-LAX are scheduled to get some better F seats?
