I don’t know if it will, but I agree with the author of [1] that it should. Python should aim to be faster in its next iteration, as it is increasingly being used for long running computational tasks like science experiments. I would go further and argue for direct integration of numpy into the language to achieve faster performance.
I don’t have any inside track knowledge on plans for Py4.
EDIT: see PEP 523
