The problem I find with Gigalith in Singles as a Sand setter is that you stack another Fighting weakness with Excadrill and with Tyranitar. Hippodown has some Spe problems coupled with a bad 4MSS, which often made it pressured by the opponent to click recovery. I don't think that can retaliate a room for itself in OU.
High hopes for Torkoal (and A-Ninetales) in OU as new weather setters. Torkoal has a nice role compression: sets Sun + has SR + Rapid Spin (in this generation Rapid Spin is spammed everywhere...). I hope that weather wards are coming back!
Cryogonal has a very good boost in its base stats (+10 HP and +20 Def) which desperately needed. Now it is a spinner that might survive a physical hit ===> UU ? Flavour wise, it needed to have Snow Warning and it is a shame it still has only Levitate (even though it is good).
Poor Gengar, is still OU material, but now it will lose a free immunity provided by Levitate. This means that now has less switch-ins opportunities (numerical bulk isn't everything), but still remains a strong SpA attacker.
