I know the entity bean in EJB2 is replaced by EJB3 JPA and MDB is still part of EJB3.
What about session bean is EJB2? Is session bean still in EJB3?

I was told that EJB3 is a blend of Spring and Hibernate. Is it true?

Session beans are in EJB 3.

JPA is a blend of Spring and Hibernate. Another way of looking at is that Spring and Hibernate are implementations of JPA.
