They never mentioned this at all.Still can't believe that bungie is selling the very thing they promised they weren't going to sell. Lol such hypocrisy. And the price!
What they discussed specifically when it showed up in data mining was consumables which would increase your chances of getting Loot drops (3 of Coins style), which at any rate were (allegedly) going to be sold by the Speaker and not for real money.
They curiously ignored the issue of level boosters completely when they made their comments, which basically confirmed it was in the works.
You may like it or not like it, but there's no need to muddle up the waters by saying they're "doing the very thing they promised they wouldn't".
