To me, the way they specifically mention Gaim or Saber seems to imply one item will be meant for the rider (i.e the Gaim face-plates or Seiken Emblems), while the other is the gimmick item everyone can use (the Lockseeds or Wonder Ridebooks).

I'm not too worried, multiple riders has (for better or worse) effectively become the norm. I just hope their names are slightly more conventional/typical.

If this is how it works, my main concerns are if this means the driver will be a chunky box to hold all the sounds for everyone. And if it can be hacked by using IR signals or pressing some tabs to unlock other forms/sound effects. After the last incident, I'm not exactly excited to hear about the people uncovering new forms by messing around with the driver.
