As of now, Malaysia has invited Tejas just for more opinion process. It will be a good platform for HAL to invest in marketing and technical proposals.
Yep. It's only an RFI. Even they will take a year or more to release the RFP. It depends on what they are asking. They are asking for something like the Hawk and M-346, which do not carry radars, and also fully fledged fighters like LCA and JF-17, which have radars. So it's likely they are not looking at AESA radar. If they want a regular 4th gen configuration that can go supersonic with a reasonably modern cockpit, then LCA Mk1's avionics configuration already fits the bill.
If they ask for something more advanced than Mk1, then I do not know how Hawk, Yak etc fit in.
We have significant political influence over Malaysia though, especially now that we are militarising A&N Islands.
Other than that, with Israeli HMD and radar its not going to work with them. Yea we need to test an new HMD too.
The French can deliver a fully functioning radar, EW suite and Topsight HMDS, all integrated. So can the Italians.
