The next two planned launches by indus are the Hilux and Fortuner. They aren't taking any orders for Hilux anymore, and i am sure the same is true for the fortuner.
I am sure that Indus only added the immobilizer + amenities to counter the Civic, else they would've waited to introduce them in the face lift.
As to when is the face life coming? I have no idea at all, but for what its worth, the amount and volume of sales Indus is enjoying at the high end (Grande), they should not be in any hurry at all. If the Civic launch had more lasting luster maybe they would have pulled their schedule. But as that has not happened (and we can thank Atlas for that), they can probably wait a decent bit.
Facelift will involve re-tooling for molds etc which all cost $$$. Obviously indus would increase the cost, but as long as the profits are flying in I don't think they are in any hurry.
Thailand still has the current model corolla, and if the 12 months gap is real, that implies late 2017, early 2018
