lxsw20:F&P do a low current induction cooktop now, good for if you're replacing an old ceramic cook top. As you're replacing gas it probably won't make much difference to just run a 32A cable for the cooktop.
We got a quote to do that to our Two story house and it was $1700 to get wired before we did any other modifications to the countertop to fit the new hob. We decided to stay with the gas hob.
