I know this is massively off-topic (have a good well paid "retirement" Igor), but I assumed that it would be written as Dos Vidaniya instead of (the correct) Do svidanyia My Russian studies is limited to listening to Sean Connery in The Russia House, and I guess I took Dos from the latin languages. Odd.
I had the same thought. I think it's more Slavic vs Germanic/Romantic. "sv", without a vowel, doesn't exist in any word I can think of. However, in Russian, consonant clusters like that are pretty common. See also, from the article, Sberbank. I'd bet there's plenty of examples in reverse too.
vid: videt' = to see, vid as in video
anie: just a suffix like "ing" in english
"till together-seeing"
