Seems Russia will adopt a "Social Market Economy" (Rhine capitalism.)
With a liberal Russia, perhaps the Baltics and Poland may embrace reactionary politics.
Russian living standards around modern day could reach perhaps Czech levels, which for Russia's population makes a massive economy.
With a liberal Russia, eventually (21st century) I can see full reconciliation with the United States and a possible partnership for countering rising China (i can't see Russia and China adopt a full time partnership despite the economic investments.)
