I voted for 'more animations for the existing races'. Although I, too, would like to see the 'missing' races in-game, I think a higher priority should be given to more fully developing the races we already have. Being able to scratch one's head, laugh, bow, lay down (as if sleeping), point in a given direction with at least one arm (with a command like /pointright, /pointup, etc.) would be great. Being able to shake hands (or some analogous operation) would be fantastic, but I assume it would require a lot more than just an animation, seeing as it would require that your partner either accept or decline your offer to shake.
