Convincing schmonvincing. All I promised is that all strategies will do equally well.
If that's really all the information you want to preserve, then I don't understand why you bother with amnesia in Newcomb's Problem. Just offer the player two boxes, the first one contains $1K, the second contains $1M, taking both boxes triggers a bomb that destroys the second box. I'm not sure what insight into decision theory we're supposed to get from such translations.
This is equivalent to Newcomb's Problem in the sense that any strategy does equally well on both, where by "strategy" I mean a mapping from info to (probability distributions over) actions.
I suspect that any problem with Omega can be transformed into an equivalent problem with amnesia instead of Omega.
Does CDT return the winning answer in such transformed problems?
Discuss.
