It happens, trust me, I see it with products that I sell. Not so much physical appearance of our products but performance capabilities and features. Marketing is always having to back pedal because certain aspects of the product are not enabled right from the get go when the products launch. Usually it involves the software not being fully vetted, which really takes time, I never like to sell a product on what the product will do in the future, for me it is what it will do today, tomorrow may never come when it comes to business.
