Well, good for you, OP.
I can only sell small portions of gold (like 50 to 90 mil) at RMAH and even this happens only once a week.
Nothing else is getting through. Even if you'll will cut the price to 1/4 from the cheapest analogue, like 20Eur to 5. No one wants anything anymore unless it's a perfect BiS and i have yet to find something like that (been trying to do that since June).
So yes, for me D3 is dead as a dodo, unless Blizz will get a lot of new (non-account bound) unique items in the game, which is highly unlikely.
