That statement was easy to miss in Dev tracker due to the vaguness of the thread and players may not have been looking to purchase items on the GTN at that time. Certainly there was no easy point of reference to the specific items mentioned in Dev response or Thread title. Not to mention some items that had their model changed were not represented in the cartel pack artwork.
For example the Spymaster set was shown on a male, the Phantom on a female. There is no reason to think they would look exactly the same on the opposite sex.
To be sure you use the preview mode to see how an item looks on your character as Species, Body Type and Gender can all play a part in how the ensemble looks.
You do know preview mode doesn't work on Cartel packs? So I had to go buy the picture on the cartel pack was the item I was buying.
