Worst case, you waited a few months and nothing showed up. Sure you are not driving the car for a few months but it's not like you need a car right now anyways, assuming you have some wheels right now.
Best case, there is AP 2.0 and you get what you are waiting for. Moreover, if you were content in getting the AP 1.0, I am sure tesla will lower the prices on those to make them appealing as they clear out stock on those vehicles.
That being said, if everyone cases is different. IMO, if you can wait it out, wait it out. Better to be sure than live with regret.
