If you want to believe the hype of an advertisement. IPX8 is merely protection against submersion, certified to a specific depth and time which can vary and needs to be disclosed for it to be meaningful. Oasis 2, Aura One, new H2O are all the same 2 meter 60 minutes. That is just that - take device, dunk it under water that deep and long under specific conditions, and it needs to still function afterwards.
At first glance the "lesser" rating the old H2O had with IP67 appears to be less protection against elements, but not necessary. IP67 also needs to protect against submersion (true only has to be tested for 1 meter 30 min), but is dust tight on top of that.
Going from IP67 to IPX8 in Kobo's case is a step in the wrong direction, IMO. They should have gone to IP68 to retain protection against dust.
