Russia has its hands full with Free Ukraine.
An attack on Georgia would only be in response to an attempt by Georgia to reclaim its rightful territory. Russia has no cause to attack Armenia, except in the unlikely event it changes its own alliance towards the West. Kazakhstan has a small chance of such political unrest that Putin may be 'forced' to act, but that seems highly unlikely. In attack - an invasion - in Moldova seems at least a little more likely, in that a pretext exists already, but again, Russia has not had recent success of note in Ukraine; unless attacking Moldova gave Russia some unknown strategic advantage, it seems unlikely.
Why do you think you're right?
Attacking Kharkiv would both make strategic sense, and be within reasonable Russian calculation of success. Russia seems likely to make the "attempt" - if for no other reason, than to tout some battlefield success near the border. It could very well be announced, with no intention of carrying through. It seems highly improbable that Russia would again attempt Kyiv, and risk a second defeat. As for Odesa, success would be an extremely small possibility, despite the huge importance to Putin's self-esteem.
Why might you be wrong?
If Ukraine can put Russia back on the defensive, then the attack on Kharkiv will not occur. It would take a major change in the battlefield situation (or geopolitical situation) for an attack on Kyiv or Odesa to be announced.
