Tracking products in SFDC

I should be able to track a product release in Salesforce. For example, I am in the middle of creating a new product, "Marker". I have already began to market my new product, so customers keep asking my salespeople when will it be ready? 

I want the ability for my salespeople to link the SFDC opportunity to "Marker", my new product. Their response to the customer can now be, "we're currently in the engineering stage and we still have 5 more stages after that". Instead of, "we're still building it out".

This would provide much value to how we use Aha!
