I just checked in for our flight tomorrow. I booked it end of January. Everything was fine, but on our return Saturday our seats (middle and aisle) had been switched to two aisles, and right in front of the bathroom. Might work for some people, but not how we like to fly. Luckily there was one pair of aisle/middle seats in the Delta comfort section that I could switch us to. Equipment changes, so check your flights if you want to make sure you are together the way you want to be.
