My ideal wish for companions is that we have 3 of every class and they have personalities that lean towards good, neutral, and evil for each class (not locked as alignment since they are thankfully moving away from that crap.) Have as much of an equal split between sexes and races as possible as well. Obviously most of these would have to be non origin companions, hopefully we at least get one of each class for these. This would probably make the majority of people happy although I am sure there would still be complaints that some exact combination isn't what they want.
As for the OP's concern, I am sure we are getting more companions, they said before release that they were giving us the "neutral" and "evil" ones first. The "good" ones are coming.
