1: More Occults.
2: Ghost babies. If we get a baby update and we still can't have our ghosties have little spectral babies, I will be...well fine but c'mon ghost babies in Sims 3 were so cool.
3: A (free!) alien update, because the features still get messed up upon aging and they deserve better. More abilities, interactions, and even newer aliens (though that could be purchasable) would be great too, but really I just need them fixed.
In addition I hope people get their freed babies finally so that we can move on to bugging the devs for something else, like dragons. ;)
