Well, according to Jason (running 777 studios producing Rise of Flight) who recently posted about this over at SimHQ - according to his source - Oleg stepped down 1.5 years ago and Ilya has been running the show since then:

And as Jason previously has said Ilya is a good friend (they live close to each other in California) I guess the source is VERY close to Ilya
A bit weird that he posts this though, but I guess 1C will not let the lid off now the day before the release in Russia...
So, I really think that there is no "cow on the ice" as we say in Sweden
Ilya is very competent and committed to delivering top notch sims in the same way as Oleg, who will probably stay as a senior advisor and have some role in the development. This situation is maybe even better than before... Oleg gets some deserved rest and Ilya will continue the heritage just fine!
