No, MK1A is just an upgraded Tejas, not in development, IAF has ordered 83 MK1As already and production will start as per schedule.
JF17 Block-II is not better than Tejas MK1 but Block-III is very advanced compared to Mk1, Block-III is direct competitor of MK1A.
FA-50 has 0 chances of selection because British companies would not give export license to KAI again.
