Small but rather significant point, at no point does the article actually estimate the number of people willing to pay real world money for virtual items. Thus ignoring the whole concept of supply and demand. How long do you think the price would hold up if the entire 25000 unusual hats came on the market?
The biggest problem with F2P for games like TF2 is that there is no disincentive to hack. Before if you hacked you ended up, sooner or latter, getting VAC banned. Now its, download wallhack/aimbot get VAC banned, make new account and rinse and repeat. Fortunately TF2 is old enough for most of the griefers to have moved on to other games. I was admining tf2 severs in the era of clans like Mygoat, which had a whole agenda dedicated to griefing and hacking, I'm not sure a possible TF3 would survive in that. Sever operators pay with their own money and time to keep servers up and not having VAC protecting that investment of time and money could be a flaw in that model.
