In response to an above post by a Wikia contributor, there won't be a one-year gap in the series, Series 3 is basically book 3, and I believe they are somewhat merging the books so the series aren't going entirely by the books, so part of book 2 is in Series 3, I'm not entirely sure about that though. But by the time it gets to it, the last books will be out for the series to continue. It's going to be at least 2 more series regarding the books already existing... depending if they really cut a lot of stuff out or not, there are 5 books, with 2 of them being split into 2, making it 7 books in total, in theory this should give 7 series... Possibly more depending how they span it in regard to the books. You're looking at probably 1 series per year, so another 4 years, the next book, and probably the one after, will be out in that time, if not all the next books (another 2, possibly both split into 2 parts making 4 books)
