If it's an area of the game we're not ready to discuss yet we won't confirm things one way or another. Confirming information by definitively answering any question thrown at us defeats the purpose of not talking about it in the first place. That's just standard PR really. I find it odd how the author obfuscated the point to make it sound like Ryan did answer. When we're ready to reveal more about exchange type functionality in Sims 4 we'll definitely open up about it!
