Well the only competitors of Sportage currently are Vezel, juke and Vitara, and i am not being a purist.
I personally find Vitara to be better than all of the above in terms of price, handling and comfort. From a practical stand point i believe in waiting for a couple of years before buying a new model or newly launched car so that car manufacturer can optimise their vehicle in response to market feedback. I bought V2 after 3yrs of its launch and i switched to Civic X in its 3rd year as well and it has worked pretty well for me, so going by that policy i will go for Vitara if i have to pick one crossover/ SUV kinda car.
Rio and Picanto will be launched but one after the other and by end if this year.
I am not very optimistic for future of Hyundai keeping in view their current policy, because they have announced high end cars like Santa Fe, ioniq, tucson and a sedan (possibly elantra) but who knows they might adjust to the market.
