I'm watching this thread with interest for a MR I'm doing in March. For some reason NW 754 MSP-DTW was switched from 12:56 depart/3:46 arrive to 1:32 depart/4:23 arrive. This is trouble for me as I'm on DTW-FRA leaving at 5:05. I'm not sure I'll be able to make it with only :42 to connect. No luggage, of course, but I may have to do an OJ and run through the terminal.
