The 720 was called the 717 for a brief period of time. My guess is that since the DC9 was really old by the time Boeing acquired MD, and the MD95 used the same airframe, it made more sense to use up a lower number in the sequence.
I wonder what Boeing will do after the 797...7107?
Boeing changed numbering schemes when they first started building jets, so it's not hard to imagine them doing so again. My money is on 807 or 808 to get things rolling.
