Is Russia going to annex the majority of Ukraine (or even all of it)? And should they, or should a handpicked government be installed in Kiev instead?

So far, president Vladimir Putin and top-level Russian government figures have hinted at taking Kharkov, Odessa and 3 other regions. What do you think is going to be their way of solving the crisis in Ukraine, depending on the particular way the West and their fascist puppet in Kiev choose to go? Which way do you think is the most rational?
