If this book does its job, you won't need follow-up books to implement the various gear. It will have what you need for whatever gear in its simplified form (read: "This is a shotgun. Shotguns do X."), whether it's augmentation, weaponry, magic, whether from a book or from your own imagination. You don't need Chrome Flesh: Anarchy to say a Radar Sensor gives you an extra sense to roll perception with, and maybe a bonus on the roll. The structure of a system like this is fundamentally not book after book after book of more and more crunch.
If this game is made the way it looks like it's going, you don't need a book with the stats for rocket skates in order to have a piece of gear that lets you run faster sometimes.
