I would really like to see the DaShade colony... and YES the Droid Planet.
Korriban as a 20 minute jump stop to a new place would be nice, but its kinda boring since its basically a dead rock, for now. We have enough of Dantooine... time for a change.
How about Yavin 4??? or how about UTAPAU!!! Its a nice place when you look out into the cliff with all those nice buildings sticking out, and pools of life in the sink holes.
