Ok, on the topic of customization: I did not see an armor shop in the gameplay video HOWEVER there is a street that continues off screen at 39:12 of this video: https://www.youtube.com/watch?v=NfGk6VMcJsw&t=2167s
And we can see a shop that appears to sell or allow you to make augments and another that appears to sell jewelry/accessory equipment. There's also a general store/item shop next to it just off screen. So I would say that definitely points towards gear customization which, honestly, not shocked.
