Maybe "ever" was too strong of a word, but I have my doubts. )
Ukrainian politics is extremely divided, corrupted and slow-working. Even reforms that are potentially supported by 90% of population could be awaited for decades. Referendum results are easily ignored (that's already happened in 2000).
So amendments on such a controversial issue as the second official language will require a lot of work and a certain stubbornness, and I don't see anyone in our government willing to put an effort. The Party of Regions (which is relatively pro-Russian) promised something like it, but their position is precarious, and I doubt they'll take the risk. And those who'll come after them might well be from another political "camp". And so it goes...
All in all, it is something our politicians would like to postpone for as long as possible, if it suits their interests.
