Lets see do level 51-55 exist right now in the current game? No, they don't so they are 'expanding' levels. Can you go to this planet right now ? No, you can't so they are "expanding" the number of planets. Can you do any of these quests on this planet ? No, so they are 'expanding' the number of quests available. Can you use any of these new abilities mentioned in passing? No, so they are 'expanding' abilities.

Lets see exclusive items in packs meaning that you get these items from a pack. Did you get items not from packs not including the GTN? No, You did not therefore your claim of false advertising is in itself false which your own words verify.
