So the "people's republics" all announced referendums (on the subject of joining Russian Federation) to take place within the next few days, and Putin was supposed to make a TV appearance, presumably to speak on the subject. The expectation is that of course these territories will be formally annexed by Russia and this will open a legal pathway for military draft/mobilization/special slaughter operation or whatever they will call it. Putin's speech has been postponed though, likely until tomorrow.
IMO, mobilization is unlikely now. Interesting why Putin's message was cancelled or postponed, but I think that he just would say something about these referendums. But mobilizations now is unlikely.
But fact that referendums is announced just few days before it will happen, it shows how desperate these occupants is. They don't even try to make things look like in legitimate referendum. They think that if they will be part of Russia, it will stop counteroffensive of Ukraine.
