What’s next for the super ants?

One of Quantummania’s more fun moments is when we learn that Hank’s already self-sufficient ants lived 1,000 years in a day while traveling through the Quantum Realm and have now become technologically advanced. They play a big role in the defeat of Kang, so you have to wonder if they’ll back. We don’t know, but the biggest (or smallest) question might be, if they did come back to Earth, would they once again be ant-sized?
