Brandon Sanderson only wrote the last book though? (which he split in two because all the stuff Robert Jordan wanted to cram in would have been a ridiculous 2000+ page tome) so it was already going to be at least 11 books by Robert Jordan. FWIW the two Sanderson books are my favourite of the series (but they are also the ending so it's hard to say)
