I think PAF should pursue acquiring JAF F-16s as I think they will sell it - KSA will help them buy EF-2000s or F-16s Block-60.
IAF might go for F-18s and F-15s. But one thing is for sure F-35 A, B, & Cs are coming to India... As USA has no one to sell these Aircrafts - so India will gonna buy it.
F-35 sale is not likely in the short run
