In the last 6 months of 2013 Kamra has been re-tooling for Block II production and I believe the first units have rolled off the production line with ground tests completed and aerial tests to begin soon, Block II will be unveiled once all testing has been done in 2014

I do not think there is need for testing. The changes are minor on the structural side. There was a wing issue (the crash of JF17). We heard that after long testing the wing was capable to handle more stresses. I think you can find enough about that. The adding of the IFT is not a big deal. The upgrading of avionics and radar has been tested on older planes. There are pictures of those testing. As far as I know the upgrades are accepted and now serial production (after indeed upgrade of the facilities) has been started. I think you meant the qualification tests of the first block 2 production will start begin 2014. We can agree on that.
