Russia preparing to invade Georgia?

Are the following signs of imminent war between Russia and Georgia? Or rather, considering the state of the 2 countries' forces a military invasion by Russia we assume to get rid of Saakashvili?

• Russia has told NATO that any planned exercises in Georgia should be postponed / cancelled calling the exercises "provocative" and would give support to Saakashvili and encourage them to take further "aggressive action" like last year
  
• 22 ships from the Black Sea Fleet have left port for "exercises" including all of the amphibious landing ships
  
• Extra Russian forces detected on the border between Georgia and South Ossetia & Abkhazia amid heightened political tensions in Georgia with protests against the Saakashvili government, though he remains popular with the majority in Georgia. There are accusations that the protests were financed by Russia.
• Russia are still concerned about Georgia entering NATO and thus giving "relevancy" to Saakashvili
  

This all comes amid Russia finally pulling out of Chechnya after a 10 year "anti-terrorist" operation. It could just be a reminder to NATO to not accept Saakashvili, extra pressure on the current Georgian regime and/or a bit of sabre rattling to distract Putin's critics from the current economic crisis in Russia. Mind you last year's conflict was a surprise to many so who knows what could happen this time?
