I don’t think that the Russians will assault Tblisi, unless the Georgian army completely collapses.
Their quality units have removed Georgian authority from Gori down to the Black Sea and have withdrawn into the sanctuaries of OS and Abkhazia (complying with the cease fire, dontcha know), leaving the *volunteers* to predate with the support of garbage units.

I understand cjm’s rage, these are caveman tactics, pure atavistic evil. But, apocalypse is serious business, too. (Besides, Ruthenia refers to that portion of Slovakia that was absorbed by Ukraine after WWII.)
