In the pre-release documentation, Microsoft mentioned the addition of a new module for surveys. I think this is going to be a huge value addition to the product.
Voice of the Customer
Dynamics CRM 2016 includes a new survey designer to create and send out questionnaires to collect feedback from customers about your products or services. Customers can take a survey on a phone, tablet, or computer. When a customer completes a survey, rules in Dynamics CRM can trigger follow-up actions that occur immediately. Survey responses are stored with a customer’s record in CRM, so your teams see the customer feedback history as they work a sale or resolve a service case.

has this been added to crm 2016?
