So everything is stated there. Similarly, the next incarnation at the end of this Kali-yuga is also mentioned in the Bhāgavata. That will take place 400,000's of years after from this time. But His father's name and the incarnation's name and the place where He will come, that is also stated in the Śrīmad-Bhāgavatam.
So this is called śāstra. Śāstra means you can consult. Just like you consult dictionary, you consult encyclopedia, you consult so many authoritative books for understanding knowledge, similarly, if you consult, you get all information. So in this Śrīmad-Bhāgavatam it is all stated: "If you do like this, you get birth like this. If you do like this, you get birth like this."
