I don't have any numbers, but it probably depends on whom you ask. According to Wikipedia (in Russian) [1], 84% of the people in Kazakhstan can speak Russian, and 74% can speak Kazakh. Ethnically, 22% of the population is Russian, and 66% is Kazakh [2]. In urban areas, it is not unusual to encounter ethnic Kazakhs who speak Russian but not Kazakh. It is likely that the Russian language will continue to play a strong role in Kazakhstan, so many people will probably need to know both the Latin and the Cyrillic alphabets, once the transition takes place.
