I read through the links in the comment above, and I'm not convinced by many of the arguments, including the theoretical voting situations, because it seems they are quite unrealistic in practice, while the current two-party system has many times given us a bad result that would have been solved by ranked choice. I'm thinking about actual Maine politics here. (Although I grant that this has the potential to change the existing liberal/conservative dynamics entirely.)
I'm much more convinced about the argument against complexity, because I don't trust the state government much to design something clear and simple, and it's not yet clear to me that ranked choice is "simple".
I hope they do.
In any case I'm very excited to see what happens.
