The are 3 teak bots, Terran's have the human scientist. every other race just gets a different skin of the two teak bots. The old teak bot and the logo teak bot.

If you play has a custom race you get the old teak bot with the old skin. 

I this final or are they implementing more?

I agree at the very least all the major's should have their own scientist type with a selection of options for the custom races

The Drengin should have a Torian slave scientist, for no self respecting Drengin will become a pencil pusher if he can whip the desired results out of a hapless slave; And when that one fails there are always others available for replacement, leaving the failure to become Torian rump roast.

I miss the hot blonde chick in the old version of GC who got a scar and an eyepatch if you took the evil morality path.

I agree with you that this is not and should not be their primary focus right now, but keep in mind artists won't be fixing stability and adding features, they will be working on art assets for this or another project. The artists and the programmers and game designers are normally not the same people.

This issue is more likely to be one of controlling project costs, and freeing up the time of the 3D artists who may be working on StarDocks other projects; they are a business and need to make a profit so I can appreciate they will have a budget for this project that has to be controlled. Having said that I think people underestimate the impact of atmospheric touches like this on peoples enjoyment.
