Actually we have seen 601,602, 603 and 604 in PAF livery which mean 26+4=30 JF-17B in total as per current status in published articles and pics
Additional JF-17B produced or spotted in Pakistan other then current 8 JF-17B shown in roll-out ceremony are posted below, keep in mind the official photo release for the rollout ceremony of the latest batch of 8 JF-17B produced in Pakistan shows
at least 10 JF-17Bs
