Well Delta through Cincinnati, let me give you the biggest piece of advice:
Try to predict which gates the flights will arrive and depart from. YOu could pull the flight status of the same flight you are going to take, but just check today's status. That will give you what the gate asignments were today. Its not a guarantee, but its a predictor.
You will hopefully get two gates with the same letter. A,B, or C.
If so you will be in the same concourse and in the cases of A nd B its just a matter of walking down a long straight hallway (they do have moving walkways in some spots)
If you have two different letters, that means a concurse change. To go from A->B or B->A there is an underground train located in the center of B, and one far end of A. To go to/from C to any other concourse, you will have to take the free shuttle bus. Busses run directly between each concurse and C. To go from C, just exit the concurse (its in a totally seperate building) using the doorway labeled with the concourse you want to go to both exits are in the center of the 4-armed concourse. To go from B to A, take the escalator in the center of the concrouse labeled "To C Concourse" and then there will be a bus stop at the bottom of the escalator. (It's the same as the escalator to go to the US Customs office, so if you see the signs for that, its at the same place) From A to C, go to the far oppostie end as the train station, and you will find an escalator down to the bus stop.
As for timing, if you are in the same lettered concourse you should be FINE, I always deduct 30 minutes from the given layover, so in your case I'd think I had 13 minutes. Going from B->A or A->B is probably doable, and there is a walkways alaongside the train tracks if you miss the train.
The shuttlebus though, if you have to go to/from C, I know I'd be sweating it. Thats just my opinion.
Then again, I got from from MSP terminal F to MSP terminal A in under 30 minutes, Mind you I must have looked like a blur as I ran through the terminal.
