Given that this virus can spread well before there are any symptoms and well after symptoms are gone I think there are very little evolutionary pressures on it right now and it can evolve into milder strains with pretty much same probability as more lethal strains.
If we are vigilant then the only thing that the virus might be pressure toward is having even longer asymptomatic spread and even higher survivability in the air and on the surfaces.
