Doesn't matter if it comes or not... the new Terms of Service taking effect in January officially declare that Instagram can take ANY of your pictures and content and use it however they want.
Terms of Use • Instagram
"Some or all of the Service may be supported by advertising revenue. To help us deliver interesting paid or sponsored content or promotions, you agree that a business or other entity may pay us to display your username, likeness, photos (along with any associated metadata), and/or actions you take, in connection with paid or sponsored content or promotions, without any compensation to you.

Translation: You agree that we can do whatever we want, and you're a moron if you use our service.
