Exo is not going to be putting out garbage, based on their history it will be well tested and implemented.
Also if they are using a fabric similar to the stone glacier terminus bags, it will be more durable then 500d pack cloth from my experience.
SG’s terminus fabric is the best pack fabric I’ve used, and wish they made a bag for their Krux with it, as it’s a huge pain in ass to get a bear rug into it
If exo’s fabric is comparable and they keep it with load shelf and exchangeable bags it’s going to be very good.
