Darkness and vision will play a big part in Pantheon, but they have not revealed any innate bonuses for any of the races. It's very possible that some races will have inherent improved night vision, but there will be other ways to improve vision as well such as items, spells, etc.
I hope after the class reveals are finished that they start talking about racials we already know dwarves will find it easier to acclimate to the cold but I want to know more! They could reveal the starting stats and racials of a few each month, would be exciting. Assuming they are that far along and happy with the racial / starting stats.
