I would have thought sooner from my experience. I got an email from Amazon today that worried me for a minute. It said I would be receiving a $25 deposit. I panicked until i saw that it was only from CreateSpace. In other words, it represented my royalties from the paperbacks only. 10 books in May at $2.50 a shot. I will be hearing from them soon re my ebook sales, which will be much higher numbers at a higher royalty rate.
