After the Revolution, what did Marx and Engels say would happen?

-After the Inevitable Revolution, there would be a Classless and Stateless Society Emerging, with No Poverty and Equality of Outcome, allowing Emancipation -Before this, a dictatorship of the Proletariat would be set up to Prevent Counter-Revolution. When it was Safe and Secure, the State would wither away. This seems a little like Anarchism, and not like Stalin's USSR and Mao's Communist China
