how many more books is diary of a wimpy kid going to have?

There will be two more. My final year and my new life. There will also be a movie.

There are already 5 books in the series and a new one "The Wimpy Kid Movie Diary" is due out March 16, 2010. This book is a behind the scenes look at the making of the movie. The transitioning of the first book onto the Big Screen. It is written by the author, Jeff Kinney, and looks to be a great addition to the rest of the books in the series. I am definitely going to get it for my collection.

Then there is going to be one more book, so far, coming out next fall. That's all I know about now.

Just four

sadly only one. :(

(i read it in the news paper.)
I'm going to write jeff and ask him to write more books than that.
it will be called the ugly truth.

i know there is one to seven but i want to know how many more there is going to be.
