Putin is unlikely to win this war, Ukraine have been given near unlimited anti-tank weapons by the EU/US, and have air superiority now with extra MiG's donated by NATO and TB2 drones from Turkey. Locals are set and prepared for guerrilla warfare. All the usual allies have distanced themselves from Russia. The writing is on the wall.
Is it likely that another oligarch will take his place? Is there any indication that top military might force his replacement? Is any of the economic suffering imposed now likely to force everyone to come out to the streets?
