N2102J was delivered May 26th. It has the ribbon tail and not the balloons tail, so I think it's safe to say that it's another Mint plane. N2142J was spotted at XFW also with the ribbon tail, as well as a yet to be registered aircraft (no numbers on the fuselage besides the msn of 10619 and the JetBlue tail) that has the streamers tail, so a third A321LR is in the works right now.
