As Lonestar says, who cares?
The main delays are airport related, not the couple of minutes difference such a minute speed differential will result in.
Now, if the 737 burned 2.5 % more fuel than the A321, I'll bet you the airlines would be thinking twice about purchasing one. Or if the maintenance costs and sheduling were worse. These are the things that influence their decisions, not 20 kph speed "advantages".
