It is now about 10 months after this article has been written and we can now clearly see that virtual currencies have made a come back in the games that are still adding new users, but not so for the games that have a declining user base.So this all seems to reinforce what the author is saying.But another factor that might be missing is the continued monopolization of the virtual currency providers, as no number goes down so does the competitiveness of their pricing. I look at it like oil prices, when you have one or two refineries supply one large area they can set their own price and force it on the market place.
