Here's why:
* He's still writing: Jeff Kinney is an active author and continues to release new books in the Diary of a Wimpy Kid series.
* No set limit: He hasn't announced any plans to stop writing.
* Creative inspiration: The number of books he writes will likely depend on his ongoing creativity, the reception of his work, and his personal goals.
However, he has hinted at a potential end to the Diary of a Wimpy Kid series:
* "Diary of a Wimpy Kid: Diper Överlöde" was advertised as "the final book in the Wimpy Kid series." While this could be a marketing ploy, it suggests a possible conclusion.
* He's branching out: Jeff Kinney has written other books besides the Diary of a Wimpy Kid series, like "The Big Fat Notebook." This suggests a willingness to explore new stories and genres.
Therefore, while we can't say for sure how many books Jeff Kinney will write, it's safe to say he's not done yet.
