I don't think the issue with reading materials is that big of a deal as long as the language itself stays the same. Alphabets are easy to learn. From personal experience, one big hurdle is going to be learning how to type in a different character set, for people who already have the muscle memory for a Cyrillic keyboard. Also, hopefully they take a sane approach to orthography, but characters like ы and ж and щ don't have a 1:1 counterpart in Latin.
