What will be very interesting to watch are the cultural developments around the stove: Wok cooking without gas is unimaginable to many people, what's a possible solution here? Roasting/blackening vegetables over gas in Indian and other cuisines. Sure, you can use an electric oven, but is this really more efficient?
Personally, for me, an induction stovetop and a single gas unit is the dream. Perfect wok cooking, some veggie blackening, I can still use some (warped on electric stove) antique, thin castiron pieces from my grandparents. But the other 90% of the time, induction is just insanely more precise, fast and easy to use.
