Weren't the Born probabilities successfully derived from decision theory for the MWI in 2007 by Deutsch: "Probabilities used to be regarded as the biggest problem for Everett, but ironically, they are now its most powerful success" - http://forum.astroversum.nl/viewtopic.php?p=1649
There are a couple of recent papers on this topic:
I personally find Finkelstein's response/counterargument convincing.
Hm, Wei_Dai(2009) seems to have a notion of rationality that is quite permissive if he's convinced by Finkelstein. If rationality isn't in fact permissive and instead stringently requires diachronic consistency (exceptionlessness, updatelessness, pre-rational priors) then I don't think Finkelstein's arguments are convincing. And there are positive arguments, e.g. by Derek Parfit, that rationality is normatively "thick".
