Anyone else think Kendrick's next album is going to be viewed as a disappointment regardless of how good it is? Following up a critically acclaimed debut is very hard in all genres, and rap is no exception. The obvious example is Illmatic. It Was Written is a great album, and arguably the second best mafioso rap album ever, it received very good reviews amongst rap circles...but it's not Illmatic.
Rappers wait their entire lives to release their debut, which is partially why so many debut albums populate "best albums" lists for hip hop. What story can Kendrick tell now, to top his own autobiographical account in GKMC? If it's not a strict concept album some will automatically say it's not as "cohesive" as his first album. If he increases his party/bullshit songs some will say it's more trivial than his first album. etc.
