While I can make no comment about your pots, cast iron, and many types of stainless steel are compatible, so any pots purchased recently should work. What I can say is it turns out all my pots worked and I didn't have to repurchase any when I got my induction stove. And it was worth it. Induction is better than gas!
You can purchase copper pots and pans right now and they won't work still, it's not the time of purchase but the material. Non-ferrous materials won't work with induction. Copper, aluminum, clay, stone, glass etc. won't work no matter when purchased.
