Well, unfortunately, the situation isn't going to change in the near future. Even without Yanukovich the ruling elite in Ukraine won't stop taking all money they can get. The longer this goes on, the less chances Ukraine has to rebuild its economy as the population is declining and the infrastructure is in decay.
Hopefully, some day a new political force will emerge, which will carry out economic reforms and fight corruption. i have several Ukrainian friends, and it's depressing that they have to leave their country in order to have some career perspectives.
But back to topic, the Ukrainian Air Force will not receive any new combat aircraft until 2025. The MoD has declared that until then upgraded aircraft will be kept in service (AIR International). It would be interesting to know how many aircraft are planned to be kept. In 2015, there will only be 160 left, and most of the current inventory will have to be retired over the 2015-2020 period.
