You're going to be waiting a long time. Python 3 happened under an exceptional set of circumstances, and given all the pain it caused, nobody is eager to do it again. It's possible that they will make a Python 4, and it's even possible that it will have some minor backwards incompatibility with Python 3. What it will not have is "You have to rewrite all of your string-processing code from the ground up."
