If you can keep them from freezing, they should overwinter just fine. I think in your area, freezes are virtually non-existent. Will they put out fruit this winter?? Sure, if they are already putting out buds, then fruit isn't far behind. But even with your southern climate, you will still see some cool temps at night this winter. Try to keep them sheltered if the temps dip to near 40 or lower. This wont kill them but will slow down their growth and production. You wont see any ripe fruit for a while, but I would say by mid-winter, you will. Good luck and be glad you are not in the upper Mid-West right now.
