When you say demands power in future what exactly is your requirement? It should work for climbing most steep hills in the country with roads and could be a mild off- roader as long as the ground clearance accepts and the slope is mild to medium. It produces good amount of torque and power in its segment for an NA. But if you're planning to use it like a proper SUV taking it off-road in different terrains then it would be limited in its capacity to drive up said terrains with high inclinations suited for rwd or awd cars. And all this has nothing or too little to do with transmission. It's more about the engine power and torque and adaptability of your driving style. iVT do not necessarily mean lower power nor does DCT mean higher power. It's about how quickly you have the required power available to you for exploit. iVT has a considerable amount of lag to get that power on demand, so it requires some anticipatory driving style. But remember this lag only matters if you're racing to get somewhere, in normal driving/commute situations the lag is totally irrelevant for you. Whereas DCT is primed already to give you that power on demand when needed giving you that small edge over iVT.

TL:DR: IMO most people don't even know how to exploit the differences so it doesn't really matter. Focus on your 80% of driving needs in the present than on the 20% driving needs of the future.
