I think something along those lines was Sean Carroll's answer to the points David Albert raised. Unfortunately, it doesn't wash! Applying the Born rule to the repeated measurement scenario tells you that the probability of the extreme branches is low; whereas, the idea that all possible outcomes occur on every trial trivially implies that the probability of the extreme cases is exactly one. The contradiction couldn't be more stark, and waffling about infinite universes isn't going to change that -- the theory gives two, mutually contradictory, results.
