2009 Syllabus Different From 2008?

This has been asked before generically but can anyone actually say whether the syllabus for 2009 is different from 2008? Are there massive changes or is just minor? The reason I ask is because I am revising from Schaweser 2008 (until I get my books from work) which wont be for another 3 weeks. Is there any danger to using 2008 revision initially?
