Personally I think Valve is trying to move everything back to the Steam Market. Thing is, why wouldn't they just remove the 7 day market buy / sell cool down for the market? It would make ita little more viable.
Also, items in CS for example have a high value ($10k+) but the steam market cap is $2k; although this limits prices I think this is a good stepby Valve since addicts will not be able to invest their life into the game.
It's ruined the game, clearly shown by dropping prices and reducing player count.
