Last time they selected EFT and suddenly a heavy jet like f15 would be a choice? I did vote for it, but later thought hardly any ToT worth will be offered. I expect gripen to be considered due to ToT on offer.
American tech is not a choice, there's gonna be far too much reliance on them if both LCA and Gripen end up with the same engine.
The IAF is more interested in airframe and engine tech in order to keep the jets more serviceable. Electronics can be changed.
While Saab comes with airframe and electronics tech, it's gonna compete with the LCA making it moot. The IAF wants twin engine 'cause it's gonna do different missions, like DPS and OCA.
