Speaking from a Polish perspective, division of Russia makes sense. Three states in the West, centered around St Petersburg, Moscow and Volgograd would partition European Russia nicely. The Volgogradia state would have the vast majority of the border with Ukraine. Then we would have a Kazan state east of the Volga which would reach to Lake Baikal, and then finally a Siberian state which would have the bulk of Russia's energy resources.
Today, it looks like the fighting has already died down. There are more and more rumours that there will be a general mobilisation on May 9th, but if this is the case, what on earth are Russia doing by letting Ukraine regroup (again!) and giving them even more time to get equipment into place?
It looks like the Ukrainian tactics right now are to simply let the Russians make small advances, but to cause them tremendous problems as they move. They don't seem to be worried about losing territory as long as they keep inflicting losses, probably because they know that the Russians don't have the manpower to actually control large swathes of territory.
In Transnistria, it seems that men are now being prevented from leaving. Could be read either way: either they want to protect themselves against a Russian coup, or they're genuinely afraid that Ukraine will walk in. 1500 Russian "peacekeepers" won't last long given that Moldova could attack from the West, and the locals really don't have a clue what they're doing.
