How long do you believe it will take before pythons eradicate alligators in the US?

My friend showed me an article he found online where these people found a 15ft Burmese python who ate an alligator. With hurricanes causing flood, releases, and escapes, the everglades are now overrun with big snakes that are not native there. How many years from now do you believe their will be so many they will decimate the alligator population, if not completely to where alligators will be hard to find in the everglades, and found only along the Gulf?
