I think Nigeria will place a follow up order ..
it's a good possibility considering they use a bunch of outdated and "Mix-Matched" jets on whoever would supply them. I do know the Nigerians are eyeing the Su-30Ks the Russians have left waiting in their reserve storages.
but considering that China also just supplied them VT4 MBTs, ST-1 Light tanks and SH-5 Howitzers, I see them possibly acquiring more JF-17s, but not just additional jets I see them also acquiring more advanced air to ground munitions, and advanced air to air munitions. (when they had the Jaguars, they had to use outdated munitions/unguided, and very limited AAMs).
now if they could use the JF-17s precisely and in good manors so to speak, I think they will actually have quite the JF-17 in the region..
but in my own personal opinion, I think the Nigerians need to start cutting the corruption down, sending soldiers to different countries such as Pakistan, China, Russia etc. as well as standardizing their weapons (such as rely on Russian or Chinese) systems not whatever they can get their hands on.
