I know they renumbered the A320s when they reconfigured them. Those went from 3 rows of F to 4, and they changed the first row of coach from 4 to 10 which matches the MDs, 737s, and domestic 767s. Although the A319s aren't getting reconfigured but only refreshed, if you will, I wouldn't be at all surprised if they're using the same numbering system on them post-mod. In fact, I just checked and saw that both seat maps are shown on SeatGuru despite that website usually being well behind the times.
