Umm also bikes don't get major redesigns every year you know? The design team normally works on a 2-3 year cycle. This means costs can be reduced as they don't have to change moulds and tooling every year for each model. They normally just tweak components or as in this case cable routing.

Also the shop cannot help if something is damaged in transit or from the manufacturer. The manufacturer/supplier doesn't inspect every bike you know! But yes, you should ask about replacing the scratched item.

I suspect in the future that bikes will not come with saddles or handlebars so that people self-select these things. It's like that road bikes usually don't come with pedals- it's a personal choice.
