12th generation need a complete overall of the assembly line because of newer platform and it requires investment. Eventually , Corolla will come to our market but I expect there will be a delay. I also believe that 12th generation will have higher prices comparing current variants.
The good part of new platform TNGA, Toyota can deploy multiple models using same assembly line. I am not sure Indus will do that. Like corolla share platform with Rav4, Prius. Although local assembly of Hybrid is not that feasible, Rav4 could be good if assembled locally, obviously it will be cut on features if Indus do it local. Rav4 can target Sportage
